You lost a bet. You maybe aren't really a gambler, but you were absolutely sure you had this one. The thing is that it wouldnt have been so bad if the loss would have been money, as you have quite enough to spare. But now you would have to ask a mamono out for a date.
The date wouldnt have to lead to anything, but you would have to ask out the mamono girl you either really disliked, or feared, and if you wouldn't do it on two weeks, the couple guys the bet was made with would go and tell the one you feared that you had rather strong feelings for her, but you were just too shy to ask her out.
