I dropped at least few games where MC kept drooling over the LI. The ones that come to my mind:
- Love of Magic, absolutely unbearable forced main LI and a spineless schmuck MC (when it comes to her).
- Price of Power, but I'm giving it another try, I've been told it gets better a bit, but I really hated it when MC blindly always took Maria's side, especially while arguing with Emilia, who is my fav girl there.
- The Visit, there're no canon LIs here, but MC was glazing over LIs I could't stand and lewds were forced.
- Between Two Worlds
Well, tit's he biggest problem of VNs with pre-established main LIs, you either love them or hate them, your experience is totally ruined if it's the latter.
The ones that I liked / tolerated:
- Hailey's story
- Little Regina, main girl is forced and MC is definitely head over the heels, but she is a cuck queen and lets us fuck her friends, who I like a lot

- Corporate Culture, dude is drooling over "not Cece" aka Alice but she is not forced in any way.
- Lost at Birth
- Elvensang
- Young Again
