Which is the episode where Makoto (Lita) cleans her room and bakes cookies? Someone comes to the door too...

29 - Makoto cleans Motoki's room and cooks the makan malam along with Usagi - one of my favorit ep.
55 - Makoto treats Eil.
66 - where Makoto teaches Usagi to make curry.
yet, there is manga-special "Makoto's Melancholy", where Makoto cleans her room all the night :)))))))))))

Episode 21
