>>11187735Probably more than a year. Some anons are so wrong by saying that Wat is the flavor of the month for Matsuri.
In mostly of Wat zatsudan she is mentioning Matsuri in a way and what they are going to do in that day. They play a lot of games off stream and they also go out shopping.
Here is the last one I saw from Wat, she mentioned that her and Matsuri entered in a clothes shop. Wat was being the mannequin for Matsuri while she was putting a bunch of cute cloths on Wat while being loud by saying "Wat is cute" and that she is a "angel".
