WE GOT HERE PRETTY QUICKLY.\n44 MINUTES BY SUBWAY FROM MY STUDIO APARTMENT NEAR SILLIM STATION.\nSINCE I'M HERE, I SHOULD LET HIM KNOW.\n\nTHE REASON I CAME TO THIS UNFAMILIAR NEIGHBORHOOD I'D ONLY VAGUELY HEARD OF\nON SUCH A COLD DAY WAS...\nDolmaengi\nI got off. Which exit should I take?\nYou won't be able to find the exit.\nBUT WHY DOES HE SAY I WON'T BE ABLE TO FIND IT?\nJemulpo Puppy\nIf you come out through the \"Goechalgu\" exit, there's a fountain, you know?\nI'm there. I'll come pick you up soon.\n...HUH?\n\n...IT MUST BE A TYPO, RIGHT? HE MAKES TYPOS ALL THE TIME ANYWAY.\nSTILL, \"GOECHALGU\" IS KIND OF CREEPY...\nDID I REALLY NEED TO AGREE TO MEET HIM? I SHOULD'VE AT LEAST TOLD NAHI THAT I WAS COMING!\nAH, N-NO. HOW AM I SUPPOSED TO TELL HER THIS?\n\nJEMULPO PUPPY INCHEON, MALE\nOh, damn...\nI'M GOING TO INCHEON TO MEET A GUY I'VE BEEN CHATTING WITH ON AN APP! ☒☒\n[HEART-POUNDING PLANET], ABBREVIATED AS HPPV\n\nA RANDOM CHAT APP WITH A SPACE THEME,\nWHERE YOU TYPE WHAT YOU WANT TO SAY AND SEND IT,\nTHEN RANDOMLY LAND ON ANOTHER USER'S PLANET.\n\nA CHAT ROOM WITH OO HAS BEEN CREATED.\nIF THE PERSON REPLIES, A CHAT ROOM IS CREATED.\nBUT IF THEY DON'T REPLY, THE MESSAGE TURNS INTO BLACK ASH AND DISAPPEARS.\n'HPP' WAS HUGELY POPULAR WHEN IT WAS RELEASED.\nBUT AS IT WAS OVERTAKEN BY NEWER APPS, IT GRADUALLY FADED FROM PEOPLE'S MEMORIES.\nBUT HOW DID I END UP USING THIS DEAD APP IN THE FIRST PLACE?\n\nIT WAS BECAUSE OF SOMEONE I'D HAD A CRUSH ON SINCE HIGH SCHOOL!\nJIUM, WE'RE GOING TO THE SAME UNIVERSITY.\nMY LONGTIME UNREQUITED LOVE, MA SEUNGJO.\n\nTAKE CARE OF ME WHEN WE GET THERE TOO.\nI'm going to ask Hana out tomorrow.\nI think coming to Rome was the best decision I ever made!\nIT WAS BECAUSE HE HAD STARTED LIKING ANOTHER GIRL.\n\nSEUNGJO HAS STARTED LIKING ANOTHER GIRL...?\nEVEN THOUGH HE'D NEVER SHOWN ANY INTEREST IN GIRLS BEFORE...\nTHE WOUND LEFT BEHIND AS MY LONGTIME UNREQUITED LOVE CAME CRASHING DOWN WAS DEEP.\nAND ALTHOUGH I SHUT MYSELF AWAY IN MY STUDIO APARTMENT AND TRIED TO FORGET, IT WASN'T EASY.\n\nJUST WHEN I WAS WONDERING IF I'D FEEL BETTER IF I COULD VENT SOMEWHERE,\nI DISCOVERED .\n...MAYBE I'D FEEL A LITTLE BETTER IF I JUST LET IT ALL OUT SOMEWHERE?\nI MEAN, PEOPLE DON'T REALLY USE IT ANYMORE, AND IT'S ANONYMOUS.\nSO I STARTED USING HPP LIKE A BAMBOO FOREST, A PLACE TO VENT ANONYMOUSLY.\n\nI stupidly said I hoped things would work out for you, but honestly, I'm feeling weird. You know what, Seungjo? I actually like you. I've liked you for a very long time.\nUghㅠ If I'd known this would happen, maybe I should've at least told you I liked you...?\nWe talked every day... fell asleep while on the phone... you always walked me home... I guess I mistook your kindness for something more... How pathetic.\nNO ONE EVER REPLIED TO ME. BUT I DIDN'T CARE.\nBECAUSE THANKS TO THAT. THE FRUSTRATION IN MY HEART WAS SLOWLY EASING.\n\nAND THEN. ON THE THIRD NIGHT.\nI WONDER IF SEUNGJO IS WITH THAT GIRL RIGHT NOW?\nWHAT ARE THEY TALKING ABOUT, JUST THE TWO OF THEM...?\n\nWhat do people talk about when they're flirting...? I'm curious. No, I'm not curious. Well, maybe a little...\nWHAT AM I DOING? STOP THINKING ABOUT IT AND GO SHOWER AND SLEEP...\nDING\nJemulpo Puppy Stop being so interested in other people's relationships.\nMind your own damn business.\n...HUH?\n\nFOR THE FIRST TIME. SOMEONE HAD REPLIED TO ME.\nDID I... ACTUALLY GET A REPLY?\nBUT WHAT'S \"MIND YOUR OWN DAMN BUSINESS\" SUPPOSED TO MEAN?\nDolmaengi\n? What does \"Mind your own damn business\" mean?\nJemulpo Puppy\nStop feeling sorry for yourself.\n\nHUH?!\nTHAT WAS HOW IT BEGAN.\nMY CONVERSATIONS WITH A MAN USING THE USERNAME \"JEMULPO PUPPY.\"\n\nHUH, WHAT'S WITH HIS WAY OF TALKING? DID HE NEVER LEARN BASIC INTERNET ETIQUETTE?\nIS HE ACTING LIKE THIS JUST BECAUSE IT'S ANONYMOUS?\nThe world is complicated, sure, but what's with your lack of empathy? Does everything go smoothly for you whenever you're dating someone?\n? Never dated. Don't care.\nSO THIS GUY IS GIVING ME DATING ADVICE WHEN HE'S NEVER DATED EITHER?\nIf you don't know anything, then keep walking, okay? And who said you could talk to me informally?\n\nFine, I'll stop. You told me to, didn't you?\nNot telling you.\nHow old are you?\nWho says you get to decide?\nI do!\nYou think you're the only one with feelings? I have feelings too.\nUGH, SO CHILDISH!!! WE'RE NOT ELEMENTARY SCHOOL KIDS. IS THIS REALLY THE LEVEL OF HIS CONVERSATION?\nIf you're that pissed off, then drop the formality too.\n\nDESPITE THE CHILDISH FIRST IMPRESSION, MY CONVERSATIONS WITH JEMULPO PUPPY CONTINUED.\nMAYBE IT WAS BECAUSE THERE WAS NO PRESSURE SINCE WE DIDN'T SHARE ANY PERSONAL INFORMATION,\nI'm bored -_- Is there any movie I can watch to my heart's content?\nAT SOME POINT, INSTEAD OF TALKING ABOUT MY UNREQUITED LOVE, WE WERE SIMPLY SHARING THE DETAILS OF OUR EVERYDAY LIVES.\nDawn of the Dead. Watching it on Netflix right now.\nIs it that one?\n\n? That’s a zombie movie.\nIN AN ANONYMOUS SPACE, WITH SOMEONE WHOSE NAME I DIDN’T EVEN KNOW,\nYou’ll be crying because you’re scared. Want to watch it together? I’ll pause it and wait for you.\n\nBEING ABLE TO HAVE SUCH AN OPEN, UNGUARDED CONVERSATION FELT REFRESHING.\nAFTER TALKING WITH JEMULPO PUPPY FOR NEARLY A MONTH AND BEGINNING TO HEAL FROM MY PAINFUL WOUND,\nSEUNGJO CAME BACK.\nI REALLY WISH YOU'D GONE WITH ME. I KEPT REGRETTING THAT YOU COULDN'T.\nSORRY... I SUDDENLY GOT BUSY BACK THEN.\nMORE IMPORTANTLY, YOU SAID YOU HAD SOMETHING TO TELL ME!\n\nAH, WELL...\nI'M DATING HANA NOW. THE ONE I MET IN ROME.\nALONG WITH THE NEWS THAT TORE OPEN MY WOUND ALL OVER AGAIN.\nREALLY...? HOW LONG HAVE YOU EVEN KNOWN EACH OTHER?\nIT'S YOUR FIRST TIME HAVING A GIRLFRIEND.\n\nAND THIS HAPPENED SO SUDDENLY...\nWELL, I REALIZED THAT HOW LONG YOU'VE KNOWN SOMEONE ISN'T WHAT MATTERS.\nTHE MOMENT I HEARD THOSE WORDS FROM SEUNGJO.\n...Y-YOU REALLY LIKED HER THAT MUCH?\nANYWAY, CON...GRATULA- TIONS. ...WOW.\nMY HEART DIDN'T JUST BURN, IT WAS BLOWN WIDE OPEN.\nI'M SO SHOCKED I CAN'T... GET ANY WORDS OUT.\n\nI FELT PATHETIC FOR NOT BEING ABLE TO GO TO EUROPE BECAUSE OF MONEY.\n\n...WOULD THINGS HAVE BEEN DIFFERENT IF I'D TRAVELED WITH HIM?\nI SHOULD'VE GONE SOMEHOW...\nBUT HOW COULD I?\nI COULD BARELY AFFORD MY TUITION AND LIVING EXPENSES.\nTHE TRAVEL MONEY I'D PAINSTAKINGLY SAVED THROUGHOUT THE SEMESTER\nHAD NO CHOICE BUT TO GO TOWARD COVERING THE SUDDEN INCREASE IN MY APARTMENT RENT JUST BEFORE VACATION,\n\nSEUNGJO. SOMETHING URGENT CAME UP, SO I DON'T THINK I CAN GO.\nGO WITH ANOTHER FRIEND.\nI LIED BECAUSE I DIDN'T WANT TO LOOK PATHETIC IN FRONT OF THE PERSON I LOVED.\nA message from Jemulpo Puppy.\ncame to Guwol-dong to go shopping. What are you doing? They didn't have what I wanted, so I'm heading to Bucheon. I'm on my way to Yeongdeungpo. The roads are completely jammed.\nHE'S REALLY BEEN TO A LOT OF PLACES WHILE WE HAVEN'T TALKED.\nDOES HE EVEN HAVE ANY FRIENDS?\n\nWhy aren't you replying? Report that you're still alive.\nThey're dating.\nWho, your unrequited love? Good for you. Forget him.\nIS HE KIDDING? IF IT WERE THAT EASY TO FORGET, I'D HAVE FORGOTTEN HIM AGES AGO.\nWHY DID I EVEN TELL HIM...\n\n...COME OUTSIDE? IS HE ASKING TO MEET? STILL, THAT'S A BIT...\nNO, MAYBE I SHOULD MEET HIM...? STAYING BY MYSELF WILL ONLY MAKE ME DEPRESSED.\nNAHI'S AWAY FOR VACATION TOO, SO I DON'T HAVE ANYONE TO MEET...\n...FINE, LET'S GO OUT. LET'S GO DO SOMETHING.\nJust chicken? Is a late lunch okay?\n\nYeah, I haven't eaten either. You said you're in Seoul, right? I'll leave now. Where should we meet?\nHE'S COMING ALL THE WAY TO SEOUL?!\nI FEEL BAD MAKING SOMEONE FROM INCHEON COME ALL THE WAY TO SEOUL...\n...AH, WHATEVER!\nNo, no, I'll go to Incheon.
