Or you can also try the number 1 romance CN on NU. No drama i swear ! Which is the reason it's the best romance. In fact it's perfect MC with perfect (little tsundere) FL and a perfect life. It's named "Martial Arts Master" you can skip the fights if you want, romance is the best part. In fact fans nickname it Love Arts Master.
Just trying to share with you a 5/5 perfect webnovel: "Beyond?" from Andur on RR(l). It's one of the numerous works of author where the (same) MC lives one OP life among all his numerous lives with (same) FL. It's an isekai goes into isekai and damn it's sweet. Just 2 deaths from side characters though, can be a little sad.
Trying to re-explain: Author goes a list of connected works where (near) each work there is ONE life of the same (but different personality after rebirth) MC.
