I have a lot to say about Crossing the Line so let´s get started. Let me first talk about the storyline. When I first saw this, I got major Haikyuu vibes. If you don´t know what Haikyuu is, it is an anime about volleyball. If any of you are into sports animes and low-key shonen-ai, I highly recommend it. But anyways, I saw the show and to put it simply, it is like Haikyuu but gayer, if that makes sense.
I found the storyline to be very enjoyable with little confusion or any major plot-twist that could leave me crying for a week. But at the same time, the storyline felt kinda predictable but overall, it was nice. I absolutely LOVED the cast. I feel like the actors have really good chemistry and I don't think it seems forced like in other dramas. All the dialogue is very nice and fitting too, similar to SOTUS, where even one small sentence can make me get butterflies. The music in this show was nice and fitting but I don't think it was really anything spectacular. I didn't want to get up and rave every time I saw the opening but the music was still soothing at times.
This is probably one of my favorite BL dramas and I would definitely rewatch considering the length of the show itself and how much I liked it. I also think it was one of the better if not best series in HIStory. Highly recommend!
