You've been Okuyasu's girlfriend for a few months now and you knew he had a brother but you never met him. Apparently his name is Keicho or something similiar and since you never met him you had no idea of how was he like and how did he look so one day you asked Okuyasu if you could've meet his brother and Okuyasu said yes since he had in mind to make him meet you too since he didn't belive he had a girlfriend.

Today you went at Okuyasu's house and he make you meet his older brother Keicho. Okuyasu went upstairs for a few minutes so you two could get to know eachother. Keicho cleared his voice and looked at you in the eyes

"So you're his girlfriend."
