What would it be 1-11

rushed, has missing details, parts from all chapters. there's a supernatural element like time traveler or time slips, think diomt. has a ntr douche friend who lusted after mc's gf. not really sure if mc cheated before he went diomt in the toon, but in the current line he was with red and they were secretly dating, while he didn't know what to make of fmc's arrival since he was from the future and that fucked his mind i guess, since this current mc was broken up with fmc and was wtf about her being all nice and loving towards him. red might have cheated on mc as well. so the whole text below is unsure. original toon name 어땠을까 google that if you wanna see the pictures.


so in that cheat toon, seem like MC regrets leaving gf and breaking up with her cause he even dreams about it. the scene in ch 1 is him with a club girl and fmc comes to pick some of their stuff she and he talks about mc and stuff like that and how fmc is too good for him, but by then him and fmc were separated. then he has a uni gathering and then fmc goes there and greets him like nothing happened. he thinks it's still a dream, even asks her what year it is, cause he still can't believe this is happening. by now he was in a sex relationship with red hair girl, so he's mindfucked cause she acts like nothing bad happened at all. she even talks about their time together and that and agree to meet again and tells him 'i love you'. red hair is very possessive an worried about him when he did not answer(he was with fmc). then red hair kind cries cause she was so worried, they fuck and it seems they have smth more than just sex buddies, but then she gets busy with work, goes and ignores mc, even flirts with a hotter guy at the office, apparently they are dating but he wants to keep it secret from work ppl, she's afraid of rumors, how she loves mc but her position is more complicated at work, she tells him she will go home today and to tell the team, and mc thinks 'with that guy?' and gets pissed and asks when will the late meeting with that guy will end and she tells him that she's his boss and doesn't have to tell him everything and tells him to get to work. mc thinks he's an idiot, why he left gf go. remembers when he did the same thing with gf and told her to keep their break up a secret so it won't affect their plans for the future. calls red and she doesn't answer and again he think he did the same stuff to gf, and she prbly felt as hurt as he does and sees it as a punishment. gets a text from red telling him the weekend is off and sorry for no being able to meet with him. he then wishes fmc was here and she comes, he freaks out and she tells him they planed it or smth(here idk the man is going crazy lol). again he asks her when did they meet, she tells him 3 days back it's still 2015,  and she jokes how he asks questions like a time traveler would, and while they had their talk about this, his phone signal was off .. she tells him smth about fireworks, and that triggers a memory of his when he rejected fmc for a date they planed to go see them, and was stressed from job seeking. they had 600th day anniversary but he didn't remembered it and left fmc alone with see u tomorrow. back to the present and he tells her that he will go after reflecting his mistakes and not wanting to repeat them. MC thinks this is a chance to make up for his mistakes. He then sees red in a toilet where he and gf wanted to fuck(prbly freaked out cause they had no plans so ..why the fuck is she there? at a park toilet near fireworks park - cheat, date with smbdy else?), MC thinks that in a week he will break up with fmc for good, and what to do.. red take his phone and gives him work for a week overnight and takes his phone away. Flashback of mc or fmc when they broke up cause he was stressed and disliked her, and fuckboy comes into the picture, he was also mc's buddy. gf asks why he doesn't have a gf, and he tells her cause of no charm, but she tells him otherwise, he drops hints that he might like her but she misses them, he stops her and asks her for a dinner next time. A few days later, the day mc and gf broke up/separated and he thinks while he fucks red that today he must go meet her, mc thinks and asks if red will miss him. gf tells rival that today is the day she and mc met, and how she fears they will break up, fmc cries how mc forgot, rival tells her that he prbly is at work, then she tells him mc is like that, and rival tells her to break up with him, cause if a guy likes her he should be there for her, thanks him how she kinda knew smth is up but his words made it more clear, hugs her and ells her to cry it out. mc sees them and prbly wonder why she and that guy are there, she tells red to go on cause he will come soon. MC thinks smth about misunderstandings, mc asks her if they were like that from before, she denies it and tells him it's not what it seems, and how when he could not call her she was playing with him, rival steps in, blames mc  and tells gf to break it up with him cause she planed too. mc tells her off on how could she do this with a close friend of his, and how she was cheating and already planned to break up with him today, fmc tells him to trust her that it's not like that, rival steps in and provokes mc with you thought she was gonna be with you forever line. they fight fmc tells him to stop it, she asks rival if he's okay, mc tells her off as to why she is concerned for him and she tells him can;t he see his hurt, she asks him if he can see her and to go to a hospital, mc is pissed and asks her why she should take him, and if she really want to kick him out. she goes off on him how is this what he wants to ask now in this situation. blames mc for this situation cause it's what he does and rival did nothing wrong, cause mc he only thinks about himself. and mc asks her if he was such a person in the past too?(or she is..). mc thinks where did he go wrong, was it that she he couldn't contact her or she didn't want to see that, thinks about a scenario where gf and rival cheat on him, how she takes blame and that. thinks how a time slip will not make sense, if this is a punishment, and if she wants to make him feel what she did, mc thinks he can't find or have what he lost before. red is worried and asks him if he wants to go home, if it hurts or if he wants to go to a hospital, and mc thinks about why did he forget that he had this woman, and that it's time for the real goodbye with fmc.
