Watch it be Jerry.
Sure thing. Bunny wanted to be honest and felt like it was wrong of her to pursue a relationship with Yeol after kissing and wanting to date somebody else because of her insecurities (and despite liking him and regretting doing so). On the other hand Yeol has accepted that Bunny wasn't on the same page as him so he's decided to let her go.
Because there are a lot of interesting characters and it's not just going round and round. I love a good shonen ai with friends that are important to the story. Miley is one heck of a good friend.
