Inkya no Boku ni Batsu Game ni Kokuhaku Shitekita Hazu no Gyaru ga, Doumitemo Boku ni Betahore Desu

I… Misumai Youshin, am a person whose hobbies consist of social-network games and muscle training, and the type who is quiet in class… A socially awkward student, so to speak. On a certain day… I coincidentally came to know that Barato Nanami, a gyaru-type girl from my class, had to “Confess to me as a punishment game.” When I consulted with my social-network gamer friends… they simply told me, “It’s a good chance, so do your best to date her and be all lovey-dovey.” After that, I accepted the confession, but… It seems like she’s already madly in love with me, even without me doing anything?!
