I remember reading this manga years ago but I couldn't remember the title. This is similar to one-room angel but I'm sure it's not one room angel. The plot is about a guy and an angel (not sure?) and one of them sacrifices their senses or body parts for the other so one of them is probably blind. In the end one of them dies and I think the concept had something to do with 7 days or 1 week in it?

I kinda don't remember the story
Ive been looking for some with jealous and possessive MLs but most of them are on the darker side.
Was wondering if there are ones that arent super dark
< Lucky Paradise > is all right !!
< Love Bite > also seems interesting, the first chapters are worth the read !!
I'd recommend
Runaway hit (seme is a puppy dog possessive)
Die if you aren't a virgin (uke is possessive)
B-class guide (seme is possessive)
Full volume (if you haven't read already)
King's maker (if you haven't read already) can get dark
What you wish for (possessive puppy seme)
My darling signed in (possessive seme)
Ore no Kirai na Senpai
SORRY THESE ARE JUST THE ONES I REMEMBER
