Vol 4: Ch 233 - Nothing's going wrong by telling the truth
Meng asking Rei seriously again "so Lou is it really alright for me to tell my parents about the truth of what happened instead of making excuses? I think it's better to hide it first before telling the whole truth or rather I will make excuses that he is my boyfriend already for 2 years."
"What kind of nonsense of that Meng? Just tell the truth and don't make any excuses just to hide the truth." Rei speaks in Ceno
"Oh-oh-oh, Lou, Lou you forgot that I already make a vow with Mr. Fu here that I will never speak in Ceno until he will become fluent on it and that's why I ask you using the Universal Language one"
"Well I'm here and I heard it very clearly but I never heard that it will be effective today, right?"
"Oh, that's right, I will edit it out and it will be effective today. So, then Lou answer my query awhile ago if it's really alright for me to tell the truth or not?"
