STORY AND CHARACTERS. Here lies the strength of this series. Both male leads (and Kazuki) are not absolutely good or bad. We see both sides of each character. We see Kiyoi at first as a brat, user, bully, then later we realize he also feels like he's a victim. Hira, on the other hand, despite being seen as a willing victim, is also unwittingly using Kiyoi for personal, selfish reasons. Kayoma, who seems to be the most "normal" of the three, can also do the wrong things at the wrong time.
We understand where the two MLs are coming from with the help of animated scenes showing how they grew up. This is what is missing in MR. UNLUCKY CAN ONLY KISS. That series ended leaving us with no clue where the two ML's families are.
Pacing is just right: too slow, not too fast. Also there's no irritating side stories of side couples, so the focus is just on the main leads. Attention, Thai BL producers!
Also, this is the only BL I've seen so far in which the POV switched from one character (Hira) to another (Kiyoi). This switch made us see more where our main characters are coming from.
ACTING. Superb ang acting from the entire cast. Special mention is the final confrontation. Acting on that scene was spot on. Good writing, too.
TECHNICALS. Cinematography is above average, seasoned professionals obviously are behind this. Same with editing and music, above average.
REWATCH VALUE. I'd watch this over and over again, yes!
10 / 10.
