In the first place it was nemu who wants to focus on his study first. And maya understand that. He didnt disturb nemu because he know that nemu needs time to study. And while nemu was busy studying hes changing himself, i think he dont want others to think negative when they are together (like how tge mom of nwmu treat him and how the cram theacher thought that he was bullying nemu) its not that hes calm, when nemu called him he rushed outside because he misses nemu also. Thats what i understand sorry my english is not that good.
