Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout.

However, within three seconds’ appearance at a press conference, his beauty made him debut in the C-position as Zhou Ziheng’s fan, and together with his idol went trending online, on a reality show, on… Yes, it’s as you think.

But it’s not as Xia Xiqing thought.

He thought he was fishing for the alpha of the entertainment industry, only to find out after peeling off the image he displays in public that he was an innocent tsundere as naive as a primary schooler. He thought it was a script about “I slept with my idol”, but in the end it became “my idol slept with me”.

Exciting [lights a cigarette]

Xia Xiqing: Didn’t you hate me the most? Why are you hugging and not letting go?

Zhou Ziheng: You smell good.
