Recommendation for movie where ml is trying to seduce fl

Does anyone have any suggestions for a movie where ml is trying to seduce fl? Thanks in advance 

a good day to be a dog -  (SPOILER: around the later episodes, the fl's memmories of them together gets erased and now he's trying to win her over again)

100 days until you die- the male lead tries to make her heart  "flutter" and ends up doing some silly stuff
