Nataruma's Questions (2)

It starts off with the salaryman MC who is secretly in love with his boss being at a bar after the death of said boss I suppose like a wake? Anyway the boss is not really dead it turns out he's a snake spirit (Imugi I think?) Anyway during the story the snake ML runs into the MC in public but turns into a snake and MC takes thesnake to his apartment to care for it. It seems to have no memory of the MC and acts like a pet snake for a while until he transforms back into MC's human boss. The story develops they have kinky two-penis snake sex and such. Just wondered if anyone else knows the title because I can't remember and it's no longer in my lists ╥﹏╥

I can't remember the title but it was a webtoon set in a uni campus where the seme (black haired dude, comes across as a bit psycho and like he needs a good night's sleep) would keep waking up and repeating the same day unless and until he finds the uke (brown haired guy) who he ends up calling 'hyunnie' I don't remember if his name was yuhyun or something similar, but he's obsessed with keeping him alive. But it's like a zombie apocalypse at the school people are turning into the living dead and they keep running into bad situations. Any help would be much appreciated.
