The seme cheats on the uke and the uke has had enough and leaves. They end up getting back together later but I want to feel for the uke and pity him. Or just very dramatic. The uke can be depressed or just upset. Any manga like this? An example is overdose

This happens in Complex.

You could try reading Intense Rain? The seme was a playboy and the uke had enough... but then they reunite again 5 years later and the uke is insecure about trusting the seme again.

New York New York is a great one.

The first thing that came to my mind was Overdose.

K n e e l .... This is the difference between your and my eye-level.
Rai from Noblesse

Scarlet most definitely

Aishuu to a lesser extent but it still applies I think
