MKON-035 The story of my beloved childhood friend being stolen by an incredibly strong transfer student Hikari Minazuki

Jun and Hikaru have known each other since they were young. Jun is quick to fight but has a kind heart, and Hikaru loves him for that; the two are in love with each other. One day, a strong transfer student named Gouriki arrives. Right after coming, Gouriki starts hitting on Hikaru, so enraged Jun challenges him to a fight. However, even Jun, who was the strongest in school, is no match for Gouriki and gets beaten to a pulp. 'Damn it... Don't you dare lay a hand on Hikaru... Stop it!!!' BSS (I liked her first) work.
