Maybe it was too long cuz mangago cut of the gun part
Maybe the reason why mc is scared of guns is probably due to suicide or someone pointed it at him or he saved ml from that gun that's how he died.
Probably because of too much regret or sumthin, ml regressed to the past and woke up during the engagement party day. That's why mc was waiting too long for ml to arrive cuz ml's past self probably planned to not attend in the engagement party. Maybe just maybe
I read the novel, spoiler be warned!
The MC and ML got married in the first timeline. At first it was just contractual but ML fell in love with the MC actually both of them fell in love, that explains why MC have sense of deja vu. They both drive the han river and ML thought that the MC was beautiful although the MC keeps saying thaf the view from the Han river was beautiful. The bath tub with sky over view at the ceiling was because during their conversations ML asked what MC wants and MC said he wanted a bath tub because he doesn’t have one in their family house and how beautiful it would be to watch the sky while at it. The french poem was translated by MC in the first timeline and he became the ML’s french teacher. The ML kept asking the MC what he wants because he wanted to give MC what he wants but the MC said he doesn’t want anything only the ML. That was before he stole the data. After he stole the data and ML found out about it, he asked the MC why he did it. He kept asking the MC to make any excuse as to why he did it but MC didn’t make any excuse and that frustrated the ML he said that in MC’s eyes he’s not worth of being even given excused to. In one of the scene where the ML was drunk and MC came begging for forgiveness the ML said “In Se-jin’s heart there’s only his father and He-shien.” “I was not there.” “I was never there.” And that’s when all the abused happened.
Just my theory
Ok so, in the past, ml neglected mc most of the time. The ml and the mc had no emotional attachments at first, but started to develop feelings with each other over time.
At first, I thought the ml was a big asshole in the past that also sexually abused mc but turns out, this recent chapter revealed that the piss of shit older brother was the one raping mc in the past. The trauma is so bad, mc is literally having nightmares from his previous life
Well at least that cleared up some confusions that the ml is not the person who's raping MC in his nightmares HOPEFULLY that is the case
Here's why I think ml is not the culprit:
Cuz if it was the ml who was raping mc in the past, then mc should've atleast felt some sense a familiar aversion during their intercourse. The mc only felt familiarity but he did not feel repulsed of ml's touch.
The recent chap rlly showed that the real rapist in MC's nightmares is the older brother. Due to his fight or flight system was activated and mc is very repulsed or scared when the older brother appeared. Not only that, the older brother referred to him as, "ido's plaything" it really shows how much he objectifies mc and has a rapist mindset
