hajime fed nagito often recently because he was obviously concerned for nagito's frail figure, nagito however wasn't really hungry but didn't protest against it, he seemed to get aroused by it actually, plus he thought that if he gained weight he could be more useful, (especially to akane, teruteru, and mikan) even though the feeding was taking a toll on him, his clothes felt tighter but he ignored it for now, some of the others began to notice but didn't question it at first.
the class went to the diner as usual. (Yeah they all live together at a hotel) and teruteru made breakfast for everyone as usual, hajime gave nagito a bagel, nagito however was once again confused about it but didn't protest and began eating the bagel while hajime was playing with his hair. Chiaki (or 'Alter ego chiaki') seemed to notice and began floating over to them before speaking.
chiaki: "hey.. hajime this may be a odd question but.. do you.. like it when you feed nagito?"
