Spoilers
I don't remember details but the MC gets sexual assaulted and the ML loses his mind because he didn't know that the MC was working as a designated driver and whatnot.
In any case, they ended up doing in the sort of way it's usually portrayed in stories like this, in other words, con non-non (? Like very rough and all of that.
In the morning, the MC wakes up and doesn't find the ML (who just went to get food or something) and feels like shit because 1) he's literally sick lol and 2) thinks he was left behind and ignored.
That day he travels to his hometown to see his parents and stays there a couple of days. When he comes back, he finds the ML Infront of his store looking beyond restless. They talk and clear up things, but they don't officially start dating until days later because the ML wants to be considered towards the MC.
Btw, the ML punches his former unrequited love at some point.
Because he found out about the assault and has mad that the MC wouldn't leave the job, so he went to his workplace and beat up his other friend (he was the owner of the club/bar) and punched his former unrequited love because they knew about and didn't do anything to prevent it and didn't tell him about the MC working there. Basically, he was blaming them for being negligent and putting MC and that position but he was also super jealous and furious because he and MC didn't have a relationship that guaranteed his overprotectiveness since the MC drew a line and said it had nothing to do with him.

is it weird that i want this to have a chasing arc. i want to see the seme jealous
