It's so cute at first then as it went on, it grows up and ends up being so heart wrenching along side with them literally growing up. I would kinda say it's realistic cause as far as I have watched BL dramas from japan, one of the leads most likely would want to become "normal" cause it's not that quite like-able to be in such relationships in japan.

What I like is from the beginning, when they met on the sidewalk line, it was super cute! The way they told each other about their imagination on the line that if they fell out of the line, they will be attacked by some things lol it was super adorable way to connect the two leads. When they ended up living together and acting like husband and wife, everything up to that point onwards the episodes just went down-hill from there.

I kinda hate Akira's behavior, I knew he was selfish from when Akira was lowkey pursuing Yuuki but it was not consensual since he just outright kisses him first a lot of times without actually asking Yuuki first about it. You could sense that he's bad news just from there, he decided everything by himself without asking how it would feel for the other! JUST LIKE WHEN HE BROKE UP WITH HIM cause he thought that what his current happiness is not normal but what others experience such as having a wife and family is the normal happiness. He wasn't content and did not overthink it first before making a decision, for a character like Yuuki who was always imaginative but not far away from reality, I thought Akira would be more mature and guide Yuuki but he guide him on his single era and not being able to move on cause he was left confused. I JUST WISHED that he at least made Akira pay for it but it is what it is when you're in-love, you forgive easily which made me really bitter on the ending.
