LIKED:
Ren by Saito Ryusei, was well performed. Acting was great by Kamenashi Kazuya as Hiroto. And Toda Erika did well as the best friend. Not as much chemistry between FL and ML as I originally thought.
Production was good until last episode; shaky camera and zoom in too close. The cinematography was well done for the most part too. No fx that I saw. Loved when Ren and Hiroto built something together using shells and ocean glass they found on the beach.

DISLIKED:
Time Management Failed: the ending felt rushed and I wanted to see what the characters futures looked like, if they cut the time used for literally running around (especially for Kamenashi Kazuya’s character Hiroto), the girls have cell phones, could call a cab, they can afford one.
More screen time for Kamenashi Kazuya at least in the final two episodes was needed.
OST Song: one main theme song that played over and over again, to the point I muted it and hoped it would stop.
The supportive friend who worked at cafe Ayuta?, had no conclusion for his character
Disliked parents of both FL and ML
Director sucked in that often Nao and Kou had WAY too slow reactions to things. To the point that it made them seem mentally handicapped.

OVERALL: It's a decent watch, nothing really emotional or fantastic to grab the viewer. Because of Kou, it could've been listed as a Rom-Com. I wont rewatch, but many would.
