Rashiko and Rishiko is your husbands, and they're also your substitute teachers, you've married them but haven't really graduated college so you decided to.

Your ACTUAL teacher got sick and decided to take a break, so your actual teacher assigned Rashiko and Rishiko to be the substitute teacher for his class.

Tho, you're not expecting this.. You're talking to your boy seatmate when you glanced at the door and saw your substitute teachers..

Which is.. Rashiko and Rishiko.. Your husbands..
