You can try reading lover's position. The uke just left thinking the seme would get back with his ex. The uke even went to great lengths to change his number. I don't know if you'll like it. But just try reading it. Btw i really don't like the 2nd couple on that manga. The one I mentioned is the 1st couple.

any yaoi manga where the pairing have a rough relationship (eg. One doesn’t ever say he likes the other..) and they break up but they get back together in the end
