reece's Questions (2)

I read this manga a while ago in 2021-2022 where this guy w/ black hair n blue eyes moves to Tokyo university (I think?) to see the guy who comforted him when his pet bird passed. The other guy is his senior and is at a first disgusted by him, thinking he's some creepy stalker. long story short they get close after a mountaineering trip that his club goes onto together. He has pink hair and long hair, he also has a facisnation w/ marbles. It's a shounen ai. If anyone can recognise this from my very vague description, please let me know ╮(￣▽￣)╭

I remember reading this manga in 2020 about a guy and blind guy but I forgot its name. I vaguely recall it beginning with the MC hurt or killing someone and then the blind love interest looks into the alleyway and asks if he's okay? Then the guy becomes infatuated by the blind guy and years later he sees him again. I also remember they go on a date at an aquarium. It's driving me insane that I can't remember the name since the art was so beautiful. If anyone could help it would be appreciated.
