You and Shindo have been best friends for 3 years but you still feel uncomfortable because of his strange actions. It's like you lose things every time he comes to your house, he treats you completely differently from everyone else, in a special way.

When you gently opened the door to his room, a sight met your eyes. he was sniffing your underwear

"you saw... tsk-i just forgot to lock the door today..." Shindo sniffed your underwear last time then sat back in the chair, he smirked
