That's the core of Delico-sensei's works: manipulators devouring one's individuality. It was especially so when she made Tourou no Ori. Which btw she had AU djs of Tourou no Ori that were also lovey-dovey so I wonder if it's her way of making a palette cleanser. Or it's ragebait. I could never tell with her.

I remembered this really pissed me off. Now that I've reread it, Hiroi seemed like he just wanted to be the center of attention rather than sharing. It only sucks because Mine and Take really love Hiroi. However, they almost have to outwardly hate each other just to make Hiroi not feel left out.
Right when it was about to flip a switch: Mine slowly becoming the pivot of the relationship instead of Hiroi, Take unconciously becoming awared of his feeling and Hiroi slowly having a taste of his own medicine, then boom, the story ended. Author even forcefed me some nonsense post-timeskip lovey dovey extras instead of properly untangling the mess.
My balls had never been more blue.
Hiroi basically forced himself onto Take and Mine lives, devoured their senses individuality, and got away with it.
