I also have a list, but I haven't update it in 2 years:

But a few of them have open endings (14, 32) or bad endings (21, 22, 33) and annoying but cute ML (16.17. 20, 37) or a bit scummy MLs (2, 11, 22, 25, 29) iirc. For me they're fine, but in case you're not.
I just completed Ball Boy Tactics, it's so cute and fluffy. Has no break up, but there's a cold period.
I also currently watching Spirit Fingers, not yet finished it, but ML is a bit dumb so I think there shouldn't be cheating, scamming or betrayal.
And maybe:
A Calm Sea and Beautiful Days with You
An Incurable Case of Love
Love Is Better the Second Time Around as there's a plot twist on what happened in the past
