I met a strange person today...
Familiar, heart palpitating.
He gave her his soul and all his love.
Even with his pathological possessiveness, he still couldn't bear to leave her and be sad when they parted...
Erase her memory and reset a memory, just for those few days of tenderness.
(In case some friends don't understand, the content is written in a narrative style, switching back and forth between the first person and the third person, and interweaving the modern and future worlds.)
Concept: The male protagonist has a pathological possessiveness, but he still puts aside his obsession for the one he loves and chooses to give her a happy ending when parting.
