It's the white haired guy.Why?
First the blonde is not it,his pants is light colored so engk.And the three left their pants looked similar but they actually differ in color.I took a screenshot of all of the four (full body side by side in ch 3) and took a screenshot of the pants of the guy who did the deed.And ladys and gentleman its the white haired guy.
Another reasoning
The one who leftthe most/best impression is the white haired guy.The blonde is too cocky hate him,and the author is obviously pairinghim with the cook.The business man is so so.But he seems boring and such I dunno.The white haired seems the best catch,which Im sure the author intends fir it to look like that from the start.
Third reasoning,the uke said he's been doing the deed with the white haired guy in the past,and if we'll gonna follow the cliche "romantic" plot,it is actuallymuch preferred/expected for the white haired guyto end up with the uke.And he seems nice to the uke too.
Thats all~

All of you will hate him more Im telling you.He'll do worse things to the uke that will get him hospitalized.He will break the uke not just physically but also mentally and emotionally.
Fr,Out of all the characters I met he's in the top 5 fictional characters that I hate the most.
If I can sell my kidney just to get inside this freaking story and beat the shit out him,believe me I will.Then I'll slap the uke to wake the shit out of him(and then hug him cause he deserves it)

Uke comes home by himself after the kidnapping covered in blood and nearly ded, asks for divorce right then
Uke stoods up and faces head on lol
Seme is shocked
Now it's semes turn to suffer

Spoiler
I kinda surfed through some chapter in the translated ver of the novel in wattpad.Then our baby has this piano that was left to him by his mom and he played some music.The bastard heard him and told him he's gonna break the piano.Then that son of bitch called the butler to hold out lil baby down.Our lil boy begged not to do it and cried cause it was a momento left by his mother but the bastard still smashed it.
My blood is boiling.I do not care if he'll have a fucking character development.I will forever hate him.I hate him to the core.And everytime he does smth bad I wanna smash his head open and every time he shows care for the uke it makes me wanna vomit.
Just FUCCKKKKKKKKKKKKKKK!!!!
Fuck him.and his shitty ass immature personality (︶︿︶)=凸

Spoiler~
Aside from smashing the piano his mother gave him.The fucking bastard locked him in the dark basement despite the uke having a phobia of darkness.So the uke cried and screamed all night until he passed out.He did not just broke him physically from all the abuse.He broke the uke emotionally and mentally.
In the novel it took the uke more than 100 chaps to agree to the divorce.And in the end the seme came back,begged for forgiveness etc and in they basically ended up together.
Even tho the seme had a character developement and the uke forgave him.I will never accept the fact that the uke and him ended up together.That light haired guy deserves the uke more.I cant just turn blind eye to all the shitty things the seme did just because he got decieved.It does not justify all the things the uke went through.
Damn this made me cry.I felt so bad for him.I've been thinking how he thought about it for weeks(even going through so much sadness) and I know he put so much in it since its his first time doing that kind of art.And for the teachers to say that,damn I cant stop crying for him.I hope he wont give up
Same I felt really sad and that tsunoki sense Was ssssoooo rude
