D'Cup (2017)

Cute, Sweet, Simple.

This is found on the Pomthani YouTube channel, and it has been recently re-uploaded with English subs.

It's not specifically a BL, because the "main" lead characters are not in a male/male relationship with each other. However, there is a gay couple and one of the three leads is gay. (the other two leads are male & female)

I found it to be just really cute. The leads didn't really have any issues, but they helped friends/visitors in their ice cream shop solve minor issues. Very sweet. Nothing complex. Worth watching if you want to kill some time.
