Mc lives in the same apartment building as ml, he sees him often and has admired him for a long while
Ml catches a rare disease which causes him to have animal characteristics and lose control around the mc
They eventually get into a relationship, but isn't stable bc ml worries about accidentally hurting mc
It's a manga, released not so long ago
Id appreciate the help!
The plot revolves around a brother and his sister, who suddenly get transported to another world. They are summoned by a mage, who is an extraordinary asshole. The mage explains that he planned on summoning this younger sister only, to make her his bride. Older brother hates that, and instead offers himself up. Mage asshole says haha okay, and sends the sister back.
Mage explains that MC (through a bond) can supply energy for the mage. Through intercourse, obvi.
I'd appreciate the help if someone could find the title!! ╮(￣▽￣)╭
