I really appreciate that Yoi had the tact to reject him properly. Sure, it's still heartbreaking for Oji, but that's better than being stuck in that feeling. On the other hand, I feel like the arrival of Kohaku's friend, coupled with her jealousy now that she knows Oji confessed, is going to create a lot of tension. But OMG! There was also some gorgeous, heartfelt romantic tension. The animation at that point was simply amazing.
