Episode 3:
I am quite frustrated with this show. The atmosphere is somewhat similar to Living with my Step-Sister, where I like it, but it does not feel to work here as well, because there is no real overarching progress. Or maybe there is but too little of it, because we still have no idea what were the circumstances of the promise they made, and I do not think there were any clues. Unless Osanai goes berserk next episode, as they are suggesting, I will probably drop it.
