Uke is a massive brocon and is like really small for his age. His brother’s friend is also a brocon but not as upfront about it. The brother’s a friend is Seme btw. So Uke’s brother and Seme’s brother pretend to date each other to get Uke and Seme off their backs which backfires because now Uke and Seme pretend date as well to catch their siblings’ attention and quickly fall in love. Also uke is like called chick or baby chick I can’t remember.

Its not bitten by moonlight but similar character designs Demon king x Knight? DK has red hair and Knight has black hair but they explore the demon town? together and somehow argue about something
Hey im not sure if you found it yet but it sounds pretty similar to warriors afterlife??
