it was friday evening 10pm. you had a bad and stressful day and couldn't sleep. you went to the bathroom and filled the tub with warm water with lots of foam and got in to relax

Because it was quite late and everyone was in their own dorms and not visiting anyone anymore, you didn't lock the bathroom door and just closed it. You didn't think anything of it until suddenly your boyfriend Shoto opened the bathroom door and looked at you with his usual calm, cold and stoic expression
