When they said Yana was being distant and stuff, I was like "oh shit, he has something going on with Linda!". Banri still feels something for her and he stuggled to hide it there and Koko saw.. I feel sorry for her now, imagine knowing your significant other was still interested in someone else and you saw that look on their face, shit that'd hurt badly. Oka must like Yana though, she was shocked when she saw that, very sad. But I bet it will turn out that Yana and Linda are just friends or something somehow lol. Let's wait and see.
