It's pretty interesting and straightforward which is quite nice to see. The way this series made the Mls meet is so funny, both of them weren't looking well on their way which leads on them bumping to each other with one of them having a bike.

Watching this without watching all the seasons (as I'm writing this review, I had finished all of them) my experience was so perplexed just like Kuzumi because Kijima was so obvious based on literally his face and the way he moves (actor of him is so good, he really looks like he dealt with a traumatic past even just by existing on the screen) that he had a bad experience he cannot move on from but I couldn't find it out. In the end, it's quite inevitable to hate Kijima for always running away and not facing his true feelings.
Then after watching all of the seasons, and rewatching this, you can finally have reasons and understand Kijima. Here you can see he was deeply hurt from the point of numbness that when he bumped to KZ, he made the opportunity to reach out to him to maybe feel something while also fooling him which had consequences, he didn't realize how precious KZ's feelings were towards him, he knew that KZ ended up falling in love with him sometime including himself but he never knew it was that deep, maybe he got reminded of his past feelings where the other didn't commit thus made him scared to accept KZ's feelings.

I think if it's your first time watching this, you'll end up maybe not liking it by the way Kijima treated Kuzumi through out the whole series or how the story literally just revolved between the two of them but if you have the patience to survive watching a lot more installment that makes the story much more clearly and be understanding of our Ml's history and his upbringings also it gets more entertaining from one installment to another. it's for you.

KZ is my boy, this dude was purely just in-love and reached out for it with all his might which KJ needed cause it compliments his arrogant and stubborn personality. I just don't like how they made his character so little on story when it comes to themselves like in here, he was just made to be the person of interest of KJ without giving much info about KJ's life, I wanted to get to know about him but they didn't do that which also made a lot of viewers dislike him cause they couldn't connect with him (including me sometimes but he was just too innocent and kind, ambitious when it comes to love which is super rare like KJ better treat him right)
