Hotaru seemed embarrassed when Kisa grabbed his hand, but she just smiled and giggled.
No, please, no adding -chan! It sound kind of too... cute for a guy.
Kisa laughed at how embarrassed her looked and right at Hotaru. "But you are cute.~" Kisa teased as she tightened her grip on Hotaru's hand, only slightly. She sighed and shrugged. "Alright then, Hotaru-kun." Kisa poked Hotaru's cheek with her free hand. "But that's all you're getting." Kisa seemed a little shocked when her ruffled her hair and smiled.
I'll gladly accept your invitation to go somewhere with you... you mind going with me through the park?
Kisa's expression went from surprised to super happy, in seconds. "Kay!~" Kisa pulled on Hotaru's cheek with her soft hands and smirked. "We are going to be buddies from now on, kay? So you won't back away from me, right?"
