https://www.mangago.zone/read-manga/sierra_to_juliet/ ; seme is insecure & has been hurt by his family & others. uke guides & comforts seme when no one else was ever able to help him. seme falls in love with uke because uke always chooses him first when seme was already treated second.
https://www.mangago.zone/read-manga/the_world_without_you/ ; seme struggles heavily & the uke helps him as much as possible, something happens & they fall out, seme regrets his actions & gets worse after losing uke (they end up together though, don’t worry.)
https://www.mangago.zone/read-manga/the_secret_of_the_depths/uu/br_chapter-288507/pg-1/ ; uke saves seme in a past life from dying, they get reborn & seme is crazy obsessive (content warning for this one)
Uke that takes care of the seme because he's depressed/heartbroken? Does this kind of plot exist?
