By complex, do you mean that
the MCs will do stuff such as : i dont think he really love me / he deserves a better life / i want to escape then one of the MC running away,
or do you mean complex because it’s a plot that makes drama outside of their relationship, such as being a vampire/job/school/etc...

Well, it's complex couse it's way beyond romance. It starts with the tipical "friend love his best friend, but can't say it, cause it will ruin ther friendship. but something happens and they realise that they have feelings for each other and start dating". But then, the author start adding more characters and more plots, such as familly, character development, relationships of diferent kinds, trust issues, traumas, friendship, and love as something real beyond just the kiss and sex shit, but the trust, the suport, the helpping, and all of that. The more the story goes the more the autor bring development and a really nice plot and art, so it's a wonderful read, i really recommend. It does't have little love games, love triangle, or all of the cliche themes that yaoi has, its more than that. The uke it's independent, has guts and breaks that "innocent and depended uke" vibe and it's very strong and fights for his rights as a human, facing the vampires.

Ok great, because most yaois relies around these 3 words : stupidity/anxiousness/rape. Super stupid character thats assumes the worst when his BF says hi to a random girl and then rabdom men sexually harrass the uke is basically the core to the yaoi genre.
Stuff about trust issues is also annoying but as long as it doesnt go overboard it’s all good, its just that author nornally makes everything way too extra but i think this one isnot going to be baseless drama.

Yep! And before anyone says anything, Gunchan consented to the sex/assimilation with the CEO.ヽ(`Д´)ノ Proof: http://www.mangago.zone/read-manga/dalkomhan_namja/mf/ibx_chapter-55/pg-3/

DUDE. The reason why the father can't do anything but to ask Gunchan and to win his his favor by doing shit is because he's not capable of controlling him. That's basically how it is with them. Unlike Minhoon and Hyungwoo, you see them blushing and dizzy whenever they do assimilation. You barely see any of that with the side pairing.

the thing is none of it was consensual. The author has chosen to make Guchan so unrealistically indifferent to everything regarding the circumstances he's currently facing that it's dubious consent at the most even regarding the sex. I understand he's supposedly getting source material to write with in exchange, but because of he was initially forced to concede to the situation, he's more or less just making the most of a s shitty situation. On both occasions he was assaulted before sex occurred. He's had violence used on him multiple times at this point from the father vampire, and in order to maintain his 'casual' characterizations he's consented to things to smooth things over. I understand why the author has done this but in no way is this a realistic 'consensual' sexual relationship when he cannot exactly walk away from things now that he's literally being held captive by a vampire's desires.
Before I read, i wanna know, is there sexual harrasment from an antagonist? Or an antagonist being too extra, such as an ex lover or a love rival who spreads rumor/make misunderstandings that causes lots of damages?
Pretty much, i dont like it when the antagonist is going overboard just because he wants the uke(its always the uke, very rarely that the antagonist is aiming for the seme)
