Childhood friend Jin and Yui. Jin is quick-tempered but kind at heart, and Yui likes him for that, making them mutual admirers. One day, a tough transfer student named Kimon arrives. Kimon immediately starts hitting on Yui, so enraged Jin challenges him to a fight. However, even the strongest Jin in school is no match for Kimon and gets beaten to a pulp. 'Damn it... Shit... Don't you dare lay a hand on Yui... Stop it!!!' BSS (I liked her first) work.
