Help finding some of my lost BL manga/hwa?

Hi! Like everyone, I lost my list, but luckily I don’t have too much and was able to remember most of it. These are all ones I’ve read before, but I like keeping them on record, yk? I remember the outline of a few of them, but I’d like some help because I read them awhile back and can’t remember the title.

1. A Japanese Manga— uke was working at a bar and seme was in the military (I believe he was a foreigner?) I think the plot was that the seme was American and the uke wanted to latch onto him so he could have a better life but fell for him

2. Another Japanese manga— uke is blind and seme is either mafia or just tangled up in some bad stuff but he tries his best to keep the uke safe. I think the title had something to do with abyss or twilight or something like that

3. A Korean manhwa— I remember this one so vividly I just can’t think of the name lolol the plot was about doppelgängers so the uke was supposed to be a doppelgänger for this guy who supposedly killed someone but ended up finding out he wasn’t a bad guy. Uke had grey hair and the seme had black hair and a scar and called the uke piggy

If I think of any more I’ll update this
