Having two characters be polar opposites can seem like a bit of a cliche or an easy way out, but this manga owns it and does it so well! While it plays off of this trope, the characters still have their own personalities outside of just being 'positive' or 'negative', and they have the most adorable chemistry! The thing that stood out for me the most about this manga (compared to other shounen ai) was the fact their relationship was already pre-established, meaning there's no story of how they got together, and that the story really just follows their day to day life as acouple.
It's light, it's cute, and it's so refreshing to see a fluffy, truly wholesome shounen ai in a sea of yaoi garbage. I'll definitely be reading this again and again!
