What is Len doing, ice skating in pairs with Suzuki Hinata at the Festival? Does Alina know about this friendship?

They look very comfortable together, what they don't know is that Amina also went skating and has seen them. 

Suzuki walks away from Len, maybe it was because he saw Amina? Len doesn't seem to mind and entertains himself by doing some figure skating.

Well, Suzuki is gone, and Len is business as usual. Apparently, theirs was just a friendly and casual, encounter. It better be!
