Ohhhhh, that makes sense. I thought she was in a good mood because she was falling in love with a MUCH older guy. I remember Ai-Chan saying her mother fell in love with an older guy when she was young, and it tends to be common for the women in her family to fall in love with older guys.
But if that’s the case, why is the younger sister ALSO on TV on page 10?
