Oh~ That would be so cute!! I could specially with the last pup since I image her to be a girl (੭ˊᵕˋ)੭*ଘ Tsukasa would be so emotional over it too, having his little pup being born the same day as his sister. Maybe he would feel a bit guilty that he can celebrate Saki's birthday since he is in the hospital, and he hates that Saki has to spend another birthday in that place, but she doesn't mind. It's a completely different feeling, being surrounded with the warm pink walls of the maternity unit while there's this soft scent of pups. She can barely contain herself when she is waiting outside of Tsukasa's room.
Saki would totally get them matching outfits when ritk's pup turns one and Tsukasa cries the whole birthday party ;; wwww Most of the photos of that day are of Rui helping Tsukasa cleaning his tears and nose... cute I love them they are such a cute familyyy ::>_<::
