omg, the second chapter is even nicer. I like how the girl is realizing her own true feelings. And it is understandable to accept the invitation to become a couple, because the girl is kinda desperate already. "Yeah not like anyone would want to be with me anyway, no way i let this chance slip out"
Also, i just realized that, in the first chapter when the dark haired guy came to the gang since they said they had the girl, he thought it would be the long-haired girl he has a crush on. Thats why he was surprised when he saw the bob girl there.
