I really liked this very formulaic drama - Thai college students go through love angst due to inability to express honestly.
Dunk Natachai Boonprasert/Dao Nuea is in his first starring role and does an excellent job of being appealingly cute and naive.
Joong Archen Aydin/Khab Khluen has a more nuanced role. He has been apparently dating Gai since high school and this effectively means no one else has pursued him except for Nuea's ongoing unrequited feelings. As the plot unfolds we get to realise he has zero experience of love and his 'girlfriend' relationship was really as a close family friend.

When our two main leads meet up again Nuea is embarrassed by his past confession so cuts off any attempt by Khluen to start anything. He remains in the 'safer' unrequited mode pining for his love and any attempts by Khluen are seen as not genuine.
We all realise that had Khluen cleared up the non girlfriend issue there would have been more chance to show us how sweet they are together, unfortunately the writers persisted with the misunderstandings for way too long thus dragging down the momentum.

Lots of negative comments about the non C kiss when Khluen is drunk but I think it is in character with this shy person who is hopeless at words and just has everything going on internally. He admits he is dumb at love and this is true in both senses of not knowing and unable to speak.

His mother plays a lovely role and we can tell that she has twigged his feelings for Nuea and tries to encourage him to not keep everything inside himself. He also has supportive friends as does Nuea. Nuea's brother, Mek Jirakit Thawornwong/Khua Fah is the more obviously experienced actor and has a strong screen presence.

Overall I enjoyed this drama and am looking forward to the sequel with Fah as the ML.
