Wow. It's been almost 3 months since I watched this BL and I can't get over it. Small clarification: if you don't like borderline toxic relationships and lack of communication, you can move on. Although the episodes are very short and fast, I didn't get bored once. You have to be hooked in this BL, because I would tend to say that nothing happens at all, but it's quite the opposite.
First, let's talk about the way the actors play: natural, incredible, and above all fluid.
Their personalities are both very different and distinct, but that's what makes them charming. The only flaw is the end. It's neither a 'happy end' nor a 'sad end'. It's just their life, and they're happy with it. This is my first Japanese BL and I'm not disappointed.
