Looking for the title of a manga I once read.Here are some things that I remember about it, if you know what I'm looking for that would be seriously helpful

• BL Manga set in a University
• the seme was a bit flashy, kind of popular, the uke was not
• the two interned in the same lab, or were in the same department in shcool and worked in the same lab
• the seme would "tease" the uke, one thing he would do was put candy wrappers in his lab coat
• the uke had younger sibling(s), possibly more than one (i can't remember)

this is unfortunately all I can remember but if you know anything that hits these buttons please let me know 🙏🏻

Is it Sick by Kurahashi Tomo?
