Aw, I’m so proud of Kai. That’s a responsible and mature response to a rival. Having someone else notice the brightness within your girlfriend is validation of them being a genuinely good person. Someone else that can see the charm is someone with a similar genuine heart. Sometimes you can’t control your feelings even if you know they’re taken. So props for one for asking permission to confess, props on the other for allowing it and props on trusting their significant other enough to allow it.
