Hey everyone, I've been trying to find a movie since few months which my ex recommended me few years ago which I watched on Netflix please help me find it

It was something like there was a couple a boy used to play video games alot and his girlfriend left him by taking a train, the guy tried to stop her at the train station but didn't since he was unemployed

And at the end of the movie the guy got rich or something by making games, got married to someone else and they both met each other by flight cancelation and stayed In one room of a hotel

I don't remember much about the movie but it was a Japanese movie for sure and so happy ending movie
