Well, at least it's not her real boyfriend in the PV, he just acts as her boyfriend
That's already a step forward. It's probably for Feel the love.
But yeah ayu had a PV where her dancer was her bf (excluding Maro here). BALLAD was good for example.
I wouldn't rule out the option of the PV being good just becaus she has a bf there. Storylines can be interesting. Of course it can ruin if it's your real bf and he's a douche, but this time it's not her real bf. She learned from her mistake.
