Kiss Me, Liar. It's a yaoi and a man gets pregnant. I was very surprised! And so were the characters, BTW.
I've read love is an illusion and positively yours, but are there any other manga/manwha/webcomics that are similar, with unexpected pregnancies (doesn't have to be bl but especially bl)? Please recommend them to me, thank you <3
