Of course she knows he's gay she wasn't she the one who dressed him up as a girl 3 years ago and that's how they met (or maybe that was his friend??........Yeah it was his friend so scratch that) but re-read the info his friend )the seme) found out about the sis, it seems she was to do a job at X-company and turned them down to work at Y-company. Maybe she found something out and manipulated her way into working at the same company as him for some reason but my gut says it's something scary and I don't trust her

HUmmmmm, maybe its Vice versa? Maybe the sister int wants Mr seme+uke-kun to hook up. Maybe shes just using him to get closer to someone HE knows? Or maybe she knows that her brother is gay and like him, AND BAM CUPID LOVE
