Identify Looking for a japanese touching game i played, forgot the name

[yolpi]

Hi guys everything is in the title. Looking for this game , to be more specific I think there's a cell phone involved and day passes. The girl is not sleeping as in other games and maybe it's set during vacation time. I think interactions become better as the days go by. It was probably MTL too.

If u have ideas i'd like to find it again.

Thanks !
