Just completed this drama last night and loved it.
The description 'charming' came to mind.

This BL manages to gender neutralise and focus on the sweet angst of a couple starting to love. What I mean by gender neutralise is there are no specific BL tropes the story could be about 2 boys, 2 girls or 1 of each it works because it is about the couple. The whole story focuses on their gradual coming together.
There is enough depth of character building, despite the shortness of the drama a lot is contained as the back story is revealed. Honestly the 11 episodes flew by and I watched from start to finish engaged all the way.
The actors are very natural in their responses and the 'human-ness' of their love is beautiful to watch at the end I sat for a while just recalling scenes. Kang Eun Bin and Jo Hyuk Joon did an incredible job depicting the leads in a realistic and restrained way that emphasised the naturalness of their portrayal. the OST and cinematography were lovely and added to the experience, especially the use of tinted lighting (blue for blueming).
