I really wanna read this manga again but it was so long ago and I remember barely any details all I remember is that its a yaoi and that a highschooler was walking but passed out (from hypothermia I think but not sure) and a dude walking found him and took him into his apartment and when the highschooler woke up he cooked the dude something to make up for it

Yamada to shounen??

That's it!!!! Thank you so much
