I dont really care about it but im pretty sure Bella is still a virgin. Her constantly trash talking Nika about being a virgin and him not at all being affected about it could be the complete opposite to her showcased behavior of being so experienced yet she isnt.
Its hard to imagine any guy who would be able to take it up with her and at the same time is considered "good enough" by her.
Ayua and Nadia are nonstop talking about how strange it is to see Bella close to a guy, how she usually NEVER talks about any guys and their utterly overwhelmed reaction about Nika and Bella having kissed on their date. If this would be a common occurence, they wouldnt be this caught off guard.
And its not only about the traume with her sister which makes Bella less open to other people, she got bullied and assaulted a lot in her past which did lead to very strong trust issues which makes it hard for me to see her just fucking around with random guys (they are too inferior to her lol).
On another note:
I dont get all the critism and whiny comments and ratings. I get that youre frustrated that you cant just fuck bella already as she seems to need it so bad, but Nika isnt really a self-insert MC. You're a horny guy playing an avn for sex while Nika is a broken guy and the need for sex just isnt really in his mind at this point.
He isnt sad that he cant fuck her either, he just feels guilty for not being able to satisfy her. Depression fucks with your emotions badly and his mind just isnt there yet. He needs more meeting(s) with amber and probably some other relevations along the way.
But if youre unable to enjoy buildup and character progression, you could still just wait a few years, its not like there wont be lewds in the future.
