"Douitashimashite" means "You're welcome".  It is often used to reply "Arigatou gozaimasu (Thank you very much)".  It's very polite.
At Onii-chan's house, everyone (Kotone, Laika, Konstantin, Haruna, and Onii-chan) altenates chores.  I didn't like the fact that Shinobu always cooked at Hinata-sou in Love Hina...  I felt it was unfair.  So in my comic, everyone has to cook, wash dishes, and clean their rooms.
Konstantin seems to come from a quite wealthy family.  Before Konstantin moved in, Onii-chan had a very small TV, but now there is a 40 inch TV with a confy sofa in living room.  Microwavable foods are rather expensive too (have to buy for five people!).
Onii-chan is pretty good at cooking too.  He was living alone in a house before Kotone came in, so he is used to cooking.  Laika is not a bad cooker, but she uses a cooking for a sword training.  Kotone is still learning how to cook.  Comic Konstantin is the only person who can't cook in Onii-chan's house.
