Watched the latest episode. I gotta say, it was pretty cute, all those surprises and blushing.

I really like the thing Rudy and Miss Isuzu have. Also kinda cute. Anyways, the other glasses guy scares me now, and I'm pretty sure it's scaring the princess too. It's cool in a way, but daang.

Oka likes Yana and wants Yana to be happy even if it's with someone else, so shes angry that Banri is hanging out with Linda which could potentially ruin Yana's happiness which is already in the dumps.

Banri doesn't want to tell his friends about the situation now because then it would be like openly admitting that he has been hiding his secret because he doesn't trust them but actually he hadn't come to terms with his past at the beginning and was running away from and avoiding his past. Now that he accepts his past, it's very hard to tell his friends about it after all this time.

You're forgetting that she is heart broken herself. When she found out the Yana and Linda had something going on, that hurt her a lot. This is her way of taking some of her angry, pain and heart break out on someone which so happens to be Banri, because she's seeing it like: Banri has a girlfriend but is still suspiciously close to another girl who so happens to be Yana's crush, she's not thinking and thus making up conclusions in her head (like most humans do) that Banri is a lying backstaber but she's actually angry for the most part because she got hurt because she couldn't have Yana, and now she think's Yana is going to get hurt because he couldn't have Linda. So her and the person she loves getting hurt, makes her angry.

And it is hard to tell secrets like that... It's something that will change people's views on him and how they treat him. If your friend started dating a girl you dated and loved long ago, but he didn't know that you dated her. How would you tell me that you've been with his girlfriend and loved her? It's not easy to blurt out secrets...

They've known each other for what I assume is about 8 months or so. Yana wouldn't be happy hearing that after all this time. Saying he "just went to school with her" is a lie though, he was inlove with her and they were best friends...

I find it odd that you're unable to relate to this though. Would you openly tell people that you lost your memory and don't know anyone including your friends and parents? Majority of people won't because it confuses them enough already and it most likely stresses them out a lot. Mentioning it, would be difficult for them and would force them to face the truth. Banri moved to tokyo to avoid his past, many people do this in real life for less tragic situations like a breakup which affected you a lot, people will try to avoid contact and try avoid anything that reminds them of the situation.

And now that he has accepted the situation, having not told Yana and the others about his past and injury. Especially since Yana thinks he's been a good friend, Banri feels guilty that he hasn't told him about it and since he only recently found out about Yana and Linda, it's hard telling his friend that he used to be best friends with Linda and that he loved her. That could potentially ruin the relationship between Yana nad Banri. Banri doesn't want that, even though Banri doesn't mean any harm, Yana will definitely take it the wrong way.

Personally, I would just say that he was shocked (thinking about how to say it to her) and was lost on what to say next since she came out of nowhere then left right away. Another part of my conscious says it's like that just for the anime to create a problem that Banri will overcome because it will attract and ensnare viewers/watchers.
