Kio is your roommate, you feel safe with him, he's such a nice person, and you feel like you have a crush on him

and you don't know if he loves you back, or he would reject your love easily

At the cafe, you saw him sitting in the chair, he noticed you

he speak

"Oh hi my roommate! What are you doing in here?"

he asking you with a soft smile, you're blushing but you have to hide your feelings or he will notice it

You love him.
