it's somehow supernatural, the MC got introduced to his new step-brother which is actually a spirit or something, he's so good looking in the MC's pov (tall, blue eyes, and has a dark hair) but other people don't even recognize his features. the MC's also in a situationship with a sunbae he got a crush on who, apparently noticed something weird about his step-brother. please help me remember the title, thank you!! (╥﹏╥)
Ive never read it but from what ik it's reminding me of https://www.mangago.me/read-manga/the_s_classes_that_i_raised/

Can someone help me find a BL manga? I think it’s not yet completed and I’m not sure if I remember things correctly but the uke seems to have social problems,
and the seme is very curious about him. I think the latest chapter at the time was about the seme finding out that the uke could interact with their professor. Comments (spoilers) were saying that it was the uke’s uncle and that he cares about him and is trying to protect him. I just can’t get a hold of that manga anymore because of the recent problem in our mgg library (╥﹏╥). Please, if anyone... thank you heaps!!
You still have your history do you not? Is it too far back to find..?
After posting this question, I actually tried to browse my list where I segregated the manga/manhwa/manhua I want to read for my convenience. Good thing my personal lists didn’t disappear with the rest of the library, and yeess!! I found it (╥﹏╥) it’s called Love Development Live. Anyway, thnx so much!
