Hi there,
I have a few manga I would like to reread, but cant remember their names, could someone help me?

1. Yaoi, possibly shounen ai: A college student finds a tin can in his bag and exchanges letters with a hospitalized sick boy through it (space/time travel? - dont remember). It turns out the boy is his friend. A relatively new manga.

2. A story about a highschool teacher that is afraid to have a serious relationship. His former student comes to his school as a trainee teacher. In the past, he was bullied for being gay and the teacher tried to console him by kissing him and saying that dating and sleeping with a guy feels good and that he shouldnt force himself into something hes not comfortable with. Now the former student tries for a serious relationship with him.

3. and the last, again yaoi or shounen ai: A highschool boy attends a funeral of a classmate he didnt know much and sees his spirit/ghost there. He attaches himself to the student and asks him to help him clean up/out his room before his mother gets to it. The boy finds a box full of photos of himself and the ghost confeses to him. Then a car accident happens and a boy dies in it, the ghost - convinced by the student - posseses the body and gets to live in it.
   and it is definitely not this one: Me Niwa Sayakani Mienedomo. But it is the only thing I can google...

Can you help me with those three manga titles? Thanks 🙂 😀

1st one seems like Samishigariya no love letter. Chaps 1-2
3rd one is the oneshot "and the rose colored days" (chap 7) from Gekkou no Rankan ni Kuchinashi no Nioi

#2: Manazashi no Hayagane ?

I'm lazy.
