>>46075988(You) are playing baseball with the boys, and end up hitting a foul, sending the ball through an open window. Rushing up to see if you did any damage, you see that you smashed the lunch of a girl from the year below. Two of her friends try to kill you, literally, but you're able to calm them down by profusely apologising and promising you'll buy her another lunch. When that's not quite enough, you're also coerced into making a new bento for her every day for a week.
