Male betas can't get pregnant right?
Right. At least not in this manga. The author said that beta males are like people in the real world http://www.mangago.zone/read-manga/love_is_an_illusion/uu/love_is_an_illusion-chapter-43.5/3/
I like that he got scolded just a bit for talking badly about his friends. That page was just so...real. He could've easily not said anything, but instead he was honest and simply let him know he didn't like that kind of talk. So good. What amazing writing.
Also, thank god they both decided to go casual for their lunch date. It would've thrown the mood if one was more dressed up than the other. Just goes to show the power of love I guess ٩(๑❛ᴗ❛๑)۶
Do Zaizen and Kiriya actually have sex in the manga?
