This is one of the most thrilling manga that has ever captivated me to follow. It's a splendid mixture of romance, drama, comedy, and a thrilling mystery.
I love how, as the story develops, the character dynamics with each other always shift, and none of the characters, even the MC, is as simple as they seem; everyone seems to have their issues they tackle with, their plans they use, and their mindset which differs from each other, which is astonishingly executed, it's not everyday you get to find a manga or even show where every character(Including the side characters with barely shown) is depicted as an individual with their motives. The mystery isn't as big later on, but overall, the seamless turn from a romance detective-like story to a story of betrayal and characters finally revealing their masks is such a breath of fresh air. The MC starts as a shy person, and grows to be a better "Boyfriend" along the way, so do most other characters. It's one of the best.
It's pretty clear I am not the only person pointing this out; the translation is undervaluing this fascinating series. As I'm reading, the translation has grown to be better, it would be nice if some of the earlier chapters were re-translated with proper vocabulary and tenses.
