hc that rin got her first cycle during a match she ended up losing because of cramps. 13 year old sae had to help comfort her and clean her up because nobody wanted to tell her (her teammates hated her and boys were too immature) he brings pads and pain killers up to her room and they spend the rest of the day huddled under her duvet watching girly cartoons and eating candy. It grows into a little tradition where even as they grew distant and cold to eachother sae was always there for her because her periods were terrible, they'd just pretend like nothing happened shortly after, even when he returned home from Spain.
