My weekly dose of math in a j-drama. ^-^
This episode starts out with Kazuki reading a letter that he's writing to students at Edogawa high school about his time at this math school that he's in. He says that everyday of the 3 weeks he's been at this math school have been bright and he's met classmates that are very special to him. He also says that all the girls are cute, so he's been having fun everyday. But that's honestly not what's been happening (seeing flashbacks) and he wants to go back to his old school.
Kazuki finds the male teacher and asks him to help him transfer to a super normal school. He can't handle all the math and the girls. The male teacher says that Kazuki should just find love, since he can freely love any girl while the male teacher can't. He also says that it would be a pain to transfer him to another school.
Kazuki is moping again until a girl named Yuri (played by Suzuki Airi from ºC-ute) comes up to him and says "Hi" and asks if he's gotten used to the school yet. She then says some math stuff that he doesn't understand. But then she says that she thinks she's fallen in love with him and that she'll love him (Aishiteruzo~). Kazuki is in shock. Nina comes in and notices this and says that if Yuri likes him, then they should just go out, but Kazuki will still be Nina's servant during school hours.
Kazuki then stalks Yuri to find out what she's saying about him. The other girls are giddy with her for confessing her love. Sayuri finds it gross that Kazuki is just staring. Kazuki asks who Yuri is and Sayuri says that she's Uehara Yuri and she has a cute angel character. Kazuki makes a pun about Yuri being cute (because she's from the group ºC-ute, he also did this with Mami in episode 2). Sayuri tells Kazuki to be careful because Yuri is so pure and will go out with him, but might throw him out if she confesses to some other person.
The male teacher calls for homeroom and says that he's going to switch up the assigned seating to freshen up a bit later on in the day.
