One of the easiest 10-star ratings I’ve given in ages. So I loved everything about this series. That's it the review.
OК ОК
Kidding I have thoughts!

I liked characters and their story. Different point of view is used, which helps us to get into the hearts of the characters.Their feelings, their connection, friendship, support and chemistry between them … all felt so real. I liked both Saint and Shin. Both have overcome some anxious stuff in their past and had different ways to deal with that but yet they made the perfect couple ....uh uh friends and balanced each other out. OK. They are friends. They are the best of friends.
GMM believes in this???
Ohh lord have mercy ...just friends, just classmates, just neighbors.You get to see them bicker and banter (their banter was insane, one of a kind ), learn eachother by pushing buttons, flirt and they take care of each other. The chemistry was off the charts. My heart was skipping beats in a way that probably wasn’t healthy. This story ticked all my BL wishes and I can't gush enough about how much I enjoyed it. OK. I miss the kisses but I can survive it. Maybe...
The plot itself is set at a great pace with a little of everything. I get that build up I long for but also get snippets of side characters that complement the story giving you a little hope at the possibilities of their futures. A little angst and suspense, bickering and banter and some real emotional moments that had my eyes leaking a many tears.
That’s not all that’s to it though, High School Frenemy also excellently highlights friendship and positive teacher-student relationships. I am inclined to say, that what this story emphasizes is the love found in companionship, in whatever form that may take.
Another aspect which makes this story fantastic is that the characters have realistic flaws and shortcomings, which makes the story and character dynamics so much more interesting and relatable.
Their actions stem from their own experiences, doubts, and motivations, so you’ll always think, “Well, I get why they did that”.


Story - Once upon a time, two friends...… or something else entirely?
Acting/Cast - It's almost impossible to find a criticism for ... OK I am biased and please forgive me.
Music The song by Sky&Nani listens like listening to the favorite songs during a car drive. I hum away with the highs and the lows, drum with your fingers on the steering wheel, and turn volume button louder and louder while smiling and I'm trying to sing the lyrics.
Rewatch Value - Can I watch this series again for the first time? Can the aliens come and do that little luminous thing, so I can forget and watch it again?

Overall this story was very intense, captivating and moving. I enjoyed getting to see these characters and loved the finale of the story, it put a huge smile on my face.

PS
Chatjen was also amazing... He was a strong, kind, sweet, incredibly good and and I love him so much.

They sold it as a bromance, but I bought it as BL
