Endless re-read Potential

A lovers' quarrel ends with one of them hitting his head & getting post-traumatic psychogenic amnesia, forgetting his lover. Meanwhile the other party tries to use this as a chance to cut their ties and push his lover back on the "straight" line
The characters' emotions are realistic and easy to get in touch with&the emotional bond between them is strong
Plus,I personally have a thing for amnesia based plots that don't get overly dramatic, so this has already become one of my all time faves!

Due to a trauma from his first boyfriend, now Ashitaka only tops. what happens when that ex finds his way back into Ashitaka's life, asking for a second chance?
