I don't know if this fits the description accurately but you can try
1. Accidental baby (omegaverse)
2. Projection
3. The secret to winning unrequited love

It's one of my favorites
Are there any BLs where the uke has low self-esteem and constantly runs away from his feelings? Like he's actually starting to fall for the seme but due to low self-esteem, he convinces himself he's unworthy and keeps trying to distance himself (I prefer non-omegaverse, but it's not a dealbreaker)
