"Brother Chao, do you know how I figured out that you didn't do anything with Ruoyan last night?" Liu Zi bragged in Wang Chao's ear before leaving.
"Tell me, how did you know." Wang Chao also asked in a whisper, acting like he was in on some big secret.
"Hehe, this morning when I saw Ruoyan looking distracted, I teased her a few times, and she didn't even respond. I even doubted if she heard me at all and her face was unhappy."
"We all know Ruoyan has strong feelings for you. If you two really made love last night, shouldn't she be smiling from ear to ear today? Seeing her like that, I guessed that nothing happened between you two last night."
"But there's one thing I'm curious about, you said Ruoyan drank so much last night and you, Brother Chao, are a real man, why didn't anything happen between you two? I guessed, did Ruoyan get her period?" Liu Zi looked at Wang Chao eagerly, hoping to confirm his speculation.
