He only said that as a reverse psychology to either test senpai's feelings for morinaga or to push him to go after him or probably both; since it's obvious that masaki only have romantic feelings for kunihiro since the beginning
Yeah i agree, but it was just way too hypocritical coming from him. Also he was all over the place when he turned up. He used Morinaga's feelings in the past, and i cant help but believe he decided to go find him again to use them again, after everything that happened in them chapters with the brother. I cant remember it all properly now, but in the chapter with him and the brother when they meet again for the first time, if i remember right, he said in his head basically (not these words) he wished he could fall in love with Morinaga because he knew he would treat him well, and he believed he was going to basically get hurt by the brother again (id have to go look to find out the exact words). He went there wavering, but found Morinaga had moved on. Although i say all that, they did need to meet again to put closer on it all. If he turned up with pure intentions, just to clear things up then leave i wouldnt have anything to say about him.
I know im a bit late in the game, but Masaki (I think thats right) really irritated me. Saying he can bring him happiness when he has been the lord of destruction for the poor guy in the past and present.
