Sero visits Aoyama late in the evening and they spend time together. Or the time Sero finds out that Aoyama likes to paint his nails and he wants his boyfriend to do his as well.
This idea was all because my friend sparklyaoyama (now geomemesss) on insta and I thought of it, so there's that, she's so freakin sweet.
