It reminds me when Yuri meddled in fo Yohan's problem back in For Your Love. They both really care for each other in their own way. that Yohan says there's no way he'll side with teacher after seeing Yuri like this, even though it goes against his logic, tells just how much he loves and cares for Yuri. We tend to forget in a romance story but having a friend who care for you to this point, is a blessing
