Glad the are delving into Matsuri storyline (even though I know most people don't like him). He was being nosy in order to avoid talking about himself, that's pretty good storytelling by the Mangaka. The MC kis a good character too he got some development this chapter also I think that even though Matsuri was horrible to him, the MC feels guilty that he didn't notice something was seriously wrong with his best friend. The love interest is kinda boring to me , he is a good love interest by BL standars but apart from that he is kind of basic. I do like that he is not specially mature he acts like a kid.
