|At chapter 50-55 there's some new year's party shenanigans.. We learn about this middle school principal who is really mysterious and weird.. She has this secret flower garden group that only allows females to enter it. It's like some kind of lesbian harem... and it's rare for elementary students to get invited to it, but Hotaru and Mikan both somehow end up with invitations...|
Then soon after that, Mikan and the others eat some experimental mochi that contains ingredients that make the people who ate it become magnetized to each other and are stuck together for a while... Mikan and Natsume happened to both eat the same one and got stuck together... Hotaru got stuck to Luca.
After it wore off for everyone but Hotaru and Luca (I guess they ate more of it than anyone else), Mikan was about to separate from Natsume, but he grabbed Mikan's hand and told her to pretend to stay stuck with him until tomorrow... I'm not sure why... he seemed to be looking suspiciously at Mikan and Narumi-sensei when she was crying in his lap (she thought everyone forgot her birthday, but they were all holding a surprise party for her)... Narumi seems to be in some kind of trouble where his hand is black and warm, and he doesn't talk about it with Mikan... anyway... Natsume forced her to stay stuck with her that whole time, even if it meant they had to go to the bathroom and sleep together... Hotaru didn't mind being stuck to Luca at all and was her usual calm self.. Mikan was panicking because she thought Natsume might ruin her chances of going to the flower garden party... when they slept together, Natsume was in pain and he moved in close to Mikan to help relieve it...
