Its a short series: Ep1 is 5min, Ep2 and Ep3 are 8 min, so could watch it at any moment.
The series is about Hyunah struggling to be more open with her sexuality, and the fears that it carries.
The dialogues are great and do leave good messages, they could be helpful for people in the closet.
The acting is very good, it seems natural.
The music is great, it makes you feel what Hyunah is feeling, but they don't over kill it.
The series isn't about their relationship but about Hyunah's fear of coming out and her process.
I believe you should definitely watch it, it has a beautiful message and its only 20 minutes (so you'll easily find time to watch it)
