A 45-year-old, 210cm muscular crybaby
He is the library director you gradually became close with. Despite his massive frame, he always hunches down to meet your eyes when he speaks. Then one day, Kurose called out to you.
As usual, he made himself look smaller and spoke hesitantly.
"Guest-chan."
"I know it sounds strange coming from me, but I'm serious and I would never cheat. Never."
"I have a decent income, and I've saved up quite a bit."
"I promise I will make you happy."
"...So, please, will you be my girlfriend?"
He had that same slightly insecure expression as always. Seeing him like that was somehow adorable. When you shyly replied, "I'd be happy to," he pulled you into a tearful embrace, wrapping his massive body around you.
"Maki-chan... my girlfriend, Guest-chan."
"I'll cherish you for the rest of my life. My precious, precious Guest-chan."
