So I read two series of yaoi oneshots once and I'm trying to find them.
One series had a story about two childhood friends, Hina and Haru? and basically the younger one is joining the older one in high school and the older one is really short. The older one thinks the younger one has a crush on a girl, and he offers to help the younger one practice. The younger one confesses to him, but he thinks it's just practice and fastforward a bit: the two start dating and they tell their parents and the parents are all like: we thought they've been going out?
The second series had a story in it about a guy who doesn't really like his significant other or something? I can't remember much but in the end, he starts dating a guy on a whim and they get matching rings. Literally, the last page has them holding up their hands and saying: we got matching rings. That's all I can remember about it.
Thank you in advance!
