My Poison Princess Is Still Cute, Vol. 1 — Chihiro Sakutake

Poison princess Raffy and immortal knight Loren -- there never was a pair more suited to be star-crossed lovers, right? Because, well, most of the time when people are around Raffy, they kinda just...die...from her poison emissions naturally. Still, Loren only married her to safeguard humanity as part of a peace treaty with demons, so there's no way he LIKES her. As in, like-likes her. Because even if he never gets killed off forever, when he dies, it must be painful...So why does he keep acting like he absolutely adores her...?
