Don't expect a fully fledged thriller plot - it's 8 episodes of about 20 minutes (five of which are credits). The story focuses on the two main characters' relationship and how it grows, period. And you know what? That's okay! No everything need to be 32 episodes.
The story as it is is well paced, has likeable characters and surprising emotional depth. There is no unnecessary miscommunication drama, no great violence and/or answering BAMFness or such - they're both very normal, every day people despite the setting. It is a simple, entertaining show that knows what it wants to do and say.

The pluses, for me (spoiler-ish! Beware!): Yoo Han's utter absence of filter. Yeon Woo's aunt being a good parental figure for once. Next to no "he's a rapey asshole but I love him" stuff or boundary violations, and I forgive what little there is because they're teenagers and we all mess up. On screen kisses!! Hawll's eyes.

The show is overall cute and fluffy but it requires some TRIGGER WARNINGS (beware, contain spoilers)
