"Oh, Xiao Xue, you're so naughty!" Su Ruobai said bashfully.
With a quick turn, she straddled Cheng Tianxue, tickling her.
"Su Ruobai, how dare you tickle me, huh? Just watch how I handle you!" Cheng Tianxue said playfully.
She immediately extended her delicate hands to tickle Su Ruobai back.
Hehe...
A string of bell-like laughter quickly filled the bedroom.
After the playful exchange, the serious atmosphere in the room relaxed once more.
"Xiao Xue, thank you!" Su Ruobai said seriously.
"Little girl! You should call me sister now! Try calling me sister!" Cheng Tianxue said proudly.
"I won't! We were born on the same day, almost at the same time. Why should I call you sister? Why don't you call me sister?" Su Ruobai replied with a laugh.
"There's always a first-come, first-served basis, right? I got my certificate with Zhang Xiaohao first; you were after! If you don't call me sister, what will you call me?" Cheng Tianxue said smugly.
