I actually really enjoyed this first movie. I went into it thinking it was going to be some intense love story due to all the clips I've seen online but it wasn't at all. So seeing that it was lighthearted and more comedic, I actually felt relieved. I absolutely love fun, light-hearted movies.

Characters:
I liked Gii. He was super confident but never cocky. I loved how he had absolutely no shame in pursuing Takumi yet he never forced himself on him and was always aware of Takumi's feelings and his "phobia" (which was really ptsd).
I also liked Takumi. He was cute and I found myself wanting to be his friend.
The other characters were kind of forgettable though as they were not central to the plot. Some were over the top and hilarious while others were just a random face in a crowd.

Actors:
I think the actors did a great job at portraying their characters. The guy playing Gii fit the character perfectly to me and he seemed comfortable in the role. The boy playing Takumi also did a great job at portraying an awkard kid with high levels of social anxiety. I see some people complain that he wasn't a good actor but I think he is. He is playing someone still mentally suffering from a childhood trauma and he hasn't had friends (except the one guy) for a very long time. So interacting with people after that is going to be...well...awkward! Lol. So in my opinion, he did a good job too.

Story:
The overall story was a pretty good one. Mildly basic with meaningful under tones, yet not so heavy that it makes you feel sad. It was about two boys, one has a crush on the other, and they become roommates. Over time we get to see Takumi lower the invisible brick wall he has built around himself to keep other people out as he comes to terms with his feelings and how his past trauma is affecting his relationships with people.
Even though the writing and script could feel a bit corny at times, I also feel that this is what added to the comedic and fluffy charm of the film. Some silly dialogue mixed with the silly music in certain scenes had me cracking up laughing at some moments. Corny dialogue isn't always a bad thing in my opinion.
I think in the end, things wrapped up nicely with Takumi realizing certain things about himself and life in general, while also finding some form of closure for what happened to him.

Locations/Scenery:
Where on earth in Japan was this film shot?? The scenery and landscaping was absolutely beautiful! Such lush, green forests and mountains; sunlight for days; beautiful buildings and interior design. It really was a treat for the eyes and added to the upbeat, light-hearted feel of the movie.

Music:
Silly at times. Unnoticible at other times.

Overall, I would recommend this movie. Especially to those of you, like me, who love fluffy movies. I will choose a fluffy movie over a steamy movie any day and this movie gave me all the happy feels ^_^
I can see myself rewatching this many times simply for it's simplicity and visual beauty. If ever I need a break from an intense series or something, or maybe I'm just bored, I can see my self rewatching this. I liked it! Lol. But I seem to be a minority in that matter.
As long as you are not taking this film too seriously and aren't expecting something deep and riveting, you'll most likely have a good time and get a few laughs out of it.
