Your heritage is important. By Rhodry

Yui want her son Benjiro to learn his cultural heritage

She arrange with her family for him to go a cultural exchange with his cousin Himari.

But Benjiro didn't not know was that cousin was a girl.
But he switch places, he found out Benjiro was a girl. Another was he err she was dressed sorta a Japanese maid outfit. The other was he was in sorta restaurant or theme cafe. He heard of them. Back home they have something simulate back here and there.
That's probably why he dressed like this. But being a girl is something he getting used to probably her first day. So I can fake it, maybe.

But when the day when by. There few people who enjoy others were a bit rude, even a few that were drunk and horny. Oh my, how could prove this problem, how do girls solve this thing in maids cafe.
