The most boring bl I've watched this year already starts with that clichéd plot of the fake brothers that nobody can stand anymore, but now comes the worst part: 12 long episodes that have nothing to say, it doesn't seem like gay romance, it's not bromance...what does it seem like? Tedious math lessons, supporting characters that no one cares about, bad acting and a mediocre ending. The director probably had a second season in mind but forgot to make the viewer care about the story and the characters from the first season.
