Yuna was too scared to confess to Dahye and lose what they already had, I'm sure we've all been there. Then, she met Joy who she found herself starting to like. Let me remind everyone that she first met Jooyoung, tried dating her, and found it didn't work so it's not like she just threw herself at Joy as the first person she found to get away from Dahye, she really could see herself liking Joy. However, she still has those 10 years of friendship with Dahye and after all, Dahye did help her a lot when she was ostracised by all the other girls so to her Dahye has a really special place. Yes, it's irritating to see her being indecisive but she's trying really hard to reason with her feelings and not hurt anyone. Maybe she could have told Dahye sooner but she really didn't want to lose what she had and with Dahye's constant obsession with boys she just couldn't see her as a possible lesbian.
