This starts out when kokoa and Tsukune are in the cave together that is when he confesses his feelings for her.

"Why do you hate me?" Tsukune asked.
"I don't hate you, it's just why do get everything." Kokoa complained.

"Kokoa I don't want you to feel left out so will you please just be friends with me?" He said.

Kokoa didn't say anything she just collapsed on the floor.

"S-So C-Cold"

"Lets get you warmed up"

A moment passed and Tsukune was on top of kokoa keeping her warm.

"T-Thanks"

"Can I ask you something?" She said nervously.

"Yeah sure I'm all ears"

"Are you and Moka dating?"

"Why do you ask?"

"No reason."

`Am I really falling for him?` She thought.

"No I wouldn't really call it dating just a close friend"

"Phew"

"What was that?"

"Nothing." She said nervously

Kokoa began to drift off into sleep and so did Tsukune.

"Hey are you feeling ok?" He said sleepily

"Yeah I'm fine."

"Hey Kokoa?"

"Yeah?"

"Would you be willing to...Well if we get out here...Go on a date in the human world?" He said. Kokoa had a surprised look on her face.

'If Isay yes I will lose my pride and fall for him' She thought. 'But if I say no I will betray my feelings for him'

"Yes"

"Aw man I was really looking forward to being with you and did you just say yes?"

"Yup"

"Huh?!"
