Can I just say I love the friendship Kiara shares with Reine.
You can tell she really cares about her and always tried to help her, Kiara wants her to be the best Idol she can be and is always willing stop make sure she won't end up like certain undesirable members in ID or end up doing the same mistakes many girls in EN did.
Even during her birthday Kiara cried and tried to remind Reine the value of what it means to be a true Idol and I appreciate that, having a coworker that wants you to succeed at your job is rare these days.
