Help Me...

Matsumoto Takanori, a 15 year old high schooler who is a very sweet young male and lives a happy life with his mother, father, and older brother, Kouyou (age 18). Well, his father hasn't been very supportive for Matsumoto, but is very strict. However, one day he was kidnapped by a group of guys during his move-up-day party. Is Matsumoto going to survive this tragedy? Will anyone save him?
