rushed sum. no tldr. not very accurate. the text over background pictures is not fully translated(camera can't pick it up most of the time or it give back shitty tl), so parts of the sum are missing. toon = 어땠을까 12화

prbly red hair thinks about how mc suffers from love. She thinks about him idk. mc thinks the kissing is a dream, and how red is next to him. she freaks out cause he pulled it out. a random 'we're done!!'. mc thinks about his past love and his current love, all related to his selfishness. how mc thinks about how he thought he was betrayed. decides to forget all his girls(ex gf/fmc) and focus on red. because of his past experience decide not to make more mistake and ruin his future too. mc sleep talks and it makes red panicked. mc goes all 'sorry, sorry', and she wonders what's that all about.
mc gets a call about a weeding this weekend, and he ask who is getting married. the caller asks him if he didn't know, how wasn't he close to him during school years, how all the alumni decided to go.  caller asks him if he's going or if he can hear him. mc thinks about how that guy decided to get married and how the bride must be ..(gf). how he hasn't talked to them(or just her) since that night, but if they decided on that then it's gotta be good ... sees a sns page and avatar with a bride and a title that goes 'going to get married now'(or smth similar). mc thinks he decided to give up, and how come it came back to make his heart feel pain. asks the air if she's really getting married. and he goes how it should/could have been gf and him in that situation ..(not sure).
1 day before the wedding, he's pissed, and goes if he can go see and see her tomorrow without being awkward. how if only they didn't break up back then and starts to imagine him and gf happy, and she tells him she loves him. how the place next to gf might have been for him or his. tbc ..
