Forgetting is the screening of memory. Until Xu Jianwan's profile gave him a splitting headache - the way she looked at him was like looking at a person who had long since disappeared in the rain. He is just the "default personality" that was implanted, and the real him has died in another timeline. Misplaced love forces him to choose who he is between forgetting and remembering.
It rained all the time, but there was always someone waiting for him on a sunny day.
Intention: Even if fate erases your memory repeatedly, I will use every reincarnation and every story to come to you again and say "I love you" again.
