Looking for 2 yaoi manga

They're both quite old so I don"t exactly remember

1st one is about a playboy seme who has a fetish of biting people, and the uke works with seme at a restaurant and falls for the seme. I remember a scene where seme gets jealous when seme gets jealous when he saw uke getting accidently bitten in the finger by a co-worker (cliche, I know) Oh and if I remember correctly uke is a pastry chef at that restaurant, I think.

2nd one is OLD but it's about a blonde foreign seme who's very handsome but actually insecure who meets uke at university and gets attached. This one is twisted bec. If I remember there was even a scene where I think seme slashed his wrists in the bathtub or something just to get uke back.

Please if anyone could help me find either, I will be eternally grateful and will forever pray for your happiness.
