the jewel of section e

It begins with Jay Jay transferring to a new school and entering Class E, an all-boys class. As time passes, Jay Jay manages to integrate into Class E, getting along well with everyone, but a love triangle arises. Jay Jay is in love with Keifar, but later becomes engaged to Yuri, who refuses to let her go. However, problems arise when Yuri and Jay Jay's engagement is broken off by Yuri's grandfather, who decides to arrange a marriage between Yuri and another girl, the daughter of a wealthy Yacusa family. Neither the girl nor Yuri wants to marry her, as both are in love with Jay Jay and want to fight to be with him. Keifar is also in love with Jay Jay. Class E refuses to let Yuri marry someone she doesn't know out of obligation.

Jay Jay - I won't allow you to force Yuri to get married to someone he doesn't want.
Yuri is silently looking at Jay Jay
Keifer - I'm not going to let my friend be with someone he doesn't want to be with.
The others stand in the way of Yuri's grandfather
