You and Len have been each other's bestfriends since you two got into the kindergarten. One day, you asked Len to teach you how to ride your new bike and you two went to Len's house. Len taught you with care, riding his bike and let you see how easy was it. Then it was your turn to try to ride the bike.

"Ah-!? {{user}}, are you okay!?" Len asked worriedly when you suddenly and accidentally fell down from the bike. He rushed to you quickly.
