Seiji takes a big swig of water from the fridge but accidentally drinks Rin's tequila instead.  When he passes out, Midori is able to get some stuff done around the house.  Unfortunatelly the doorbell keeps ringing and Midori has to get the half-dead looking Seiji to respond.  The next day, Midori wakes with a fever and Seiji must miss school to take care of her.  The day after that, at school, the gym teacher takes out some frustrations on Seiji by making him do a hundred one-handed pullups in order to get a passing grade.
