The story revolves around 2 guys at school that meet, fall in love, suffer minor hiccups in their relationship and stay together at the end. Takara (Sato Arata) is the silent type that really cares about his significant other and is out there to help and protect him. Amagi (Oriyama Nao) is the cute, energetic kind that has his small circle of friends and enjoys every moment. He also is in love with Takara and is not not shy about voicing his true feelings although is shy in certain other matters.
Both the male leads share a great chemistry onscreen however that develops gradually and its not rather evident in the first couple of episodes. Special mention should go to supporting cast of Katori (Suzuki Kosuke) who plays the ever-helpful friend of Amagi and Tanaka (Komiya Rio) who plays the oblivious but caring friend of Takara. Katori especially plays an important role in helping the 2 leads to reconcile their issues.

Now its time to discuss the things that I didn't enjoy and the list might be long. Warning: Spoilers ahead
Ep. 1 begins with a conversation between a sorrowful Takara and a crying Amagi wherein it appears that there might have been an event due to which they are no longer in a relationship or on the verge of breaking up. This hooked me immediately as now I am intrigued to know what caused this . The scene moves to the past where we are introduced to these 2 characters and how they decide to start "dating". Now I assumed I will be taken through a journey detailing their days together and how their relationship develops further but to my utter surprise ,in a rush the issue from the beginning is revelead to just be a simple misunderstanding and they get back together. So all that crying and weeping for nothing. That could have easily been resolved by having a conversation.
And this is where the series lacks behind many other BL series with similar themes and storylines. These 2 ML do not seem to have a natural conversation. They just happen to meet daily at school, they greet each other and go into mundane topics that dont further the narrative but is just a filler to move to the next scene. Every episode is - Amagi has a simple conversation with his friends about something random, Takara and his friends talk about something generic. Amagi and Takara look at each other. Then they meet and have another conversation about something random.
So what pushes the narrative ahead if its not the dialogue between the 2 ML? Its voice-over narrations. Takara will look at Amagi and will go into a long winded voice-over narration about how he feels about Amagi or Amagi will look at Takara will have his own voice-over narration talking about the past. This is how the series progresses from one plot to the other. Its not a smart dialogue but these 2 reminiscing about something from their past.
In one of the episodes they show Amagi's past when he was a kid, ignored by his parents and that revelation and his understanding that he is always ignored and abondoned by people could have been used as a plot showing his constant need for validation from Takara about their relationship. They teased that possibility by showing Amagi speaking to Tanaka that he is the only one who is in love but nothing came out of it at the end.
On one hand we get to know about Amagi's childhood, but on the other hand we get no information about Takara. Many such opportunities of improving the story was available but it was not grabbed.I understand that this series is adapted from a manga and I have not read it so not sure if anything like this was mentioned in there. Purely judging the story presented in this series, I can state that it could have been done differently with a lot of new concepts introduced but sadly we didn't get that.
I would recommend it as a 1 time watch and should be seen especially for the supporting cast.
