>randoseru I have this sudden urge to see little bro here to hit puberty and grow tall suddenly, then enter a cute as fuck relationship with Ai's sister wherein she's the elder of the two but he looks more mature.
Man, many men would kill to be in Ai's Friend's position.
Speaking of which, today's Getsuyoubi no Tawawa episode marks Ai's Friend's debut... starting with the "groping Ai at school" scene and subsequent physical exam scenes.
Context after some research: Harutaka looks to be the place for high school volleyball championships.
春高 (Haru-kou) is the abbreviation of "春の高校バレー" (Haru no koukou baree; high school volleyball in spring), the nickname of All Japan High School Volleyball Championship.
