Please Help Me Find This Manga

Guys can u help me find this one bl manhwa? I remember that there were these special episodes where the mc and ml met but the ml was a vampire and the Mc was like a small human? portrayed kinda like a bear? The ep was written simply and w not much color but it was very touching (i remember other comments saying so as well) I can't remember if they were special eps or side stories but the vamp ml doesn't drink blood I believe and the room he lives in is super bleak with only a coffin and Mc helps liven things up but one day mc bleeds and gets driven out and there's also a christmas tree involved somewhere in the plot and ppl are hunting down ml. Sorry if this is a bad explanation! I'll keep on trying to remember more ┗( T﹏T )┛thank u!!

Yaoi btw no straighr bullshit (not that i have something agaisnt it) i need the uke to be strong and manly no looks like a 12 year old but canoinacally has 182773 years (we r not old fatty pedos) and the seme to be green flag or well in this economy not rape uke ;^ pls reccomend ♡♡♡ ٩(๑❛ᴗ❛๑)۶

I forgot if it was a manhwa or an anime but it’s a workplace setting, I think at first, the mc though the ml was like an ordinary new employee but than he finds out that ml is a manager. After that, he tries to like make it up to him or something and I remember there was a part where he mc says “do you wanna get coffee?” And the ml says no because he doesn’t like coffee. The ml also has a friend at the workplace and the friend knows that ml isn’t good w socializing nd stuff and he tells ml to ask mc to get alcohol together (this part may be wrong)
