i think hes indeed just a pure virgin waiting for real love. u see the flashback in chap 3 senpai said to give his first time to his love thats why hes a virgin till he met senpai again. theres nothing to imply that he has bottomed before too so i believe hes a virgin
His determination oof- this is beautiful
how can he be that innocent yet such a sadistic dom. truly beautiful
That's why he's previous uwu
If Mibu didn't used his dick for sex before, did he bottom? Or he's just pure virgin waiting for real love
