Hi, I'm looking for the piano sheet of the song(as title).

Here is a OP video from youtube

I also found two videos on youtube...but there are no piano sheet:(

Hope someone can help me to transcribe the piano sheet.

I wouldn't mind help you if you already have a vague chords-mapping ;-)

I found a video, maybe this will help...
