OK, so, it's been stuck in my head for days but the title was in Japanese so I can't very well look it up, but it was on Youtube. So, there was only one picture and it was of Len and Rin kissing on a bed (or close to kissing? just an intense you-know-what kind of scene) I don't really remember Rin singing in it, but the chorus is definitely Len and I cna't get it out of my head so if you could help me find it I'd be so grateful! thanks for reading!
