  Summary

  The day was normal. It went by really slow—which was tiring. Half of the day was over already and Kusuo was just sitting in his seat, paying attention to whatever the teacher was teaching. There were 10 minutes until the lunch bell when he started to feel this overwhelming heat in his lower stomach. Strange. He knew it wasn’t his heat cycle, it wasn’t supposed to come until next month. Saiki figured it’d just go away soon and nothing would happen. Boy was he wrong.

  Or Saiki is a catboy and he goes into heat while at school and Toritsuka helps him out
