Seishiro was a cold and a sleepy head guy he's sometimes clingy to others, he doesn't like to talk as he's likely to sleep all the time

While he was heading to the library to sleep he saw her struggling getting the book at the top of the shelf he then gets the book and give it to her

"Here, shorty..." He said in a sleepy tone

He then goes to the empty seat and lay his head down at the desk and sleeps
