Dino felt somehow shy upon seeing that Eric was kneeling on the ground and waiting for the former to ride on the latter's back. Moreover, Dino hated the fact that he would cause inconvenience for his best friend yet Eric was willing to do it.
[Damn. If I didn't do it with Ivan last night, I wouldn't cause this much inconvenience to Eric.] Dino thought guiltily with his eyes closed.
Eric, who was waiting for Dino to ride on his back for several seconds, turned his head and noticed that Dino's eyes were closed. Then he asked, "Dino, what are you doing? Will you get on my back or not?"
Dino reopened his eyes and declared, "Eric, I'm sorry."
"Huh? What are you sorry for?" Eric asked, looking confused.
"I'm sorry that you had to carry me because I did it with Ivan last night," Dino replied shyly without looking at Eric's eyes.
