How to evaluate the female guest Kong Ruchun in the fourth season of Heartbeat Signal?

In Heartbeat Signal 4, the least popular guest should be Kong Ruchun, the youngest. The guests who came to the program before were either graduates for many years or doctoral students, at least at the age of marriage. Kong Ruchun in the signal cabin is too different from the age of the male guests. He is not looking for the other half, more like playing.

Kong Ruchun has a simple personality and looks like the kind that boys like. Just entering the signal module, Ma Zijia and Deng Kaiwei both shine at the moment. It is not difficult to see from their attitude that they have a good impression on Kong Ruchun. If the age gap is not too big, there will be no indifference afterwards. Ma Zijia's attitude before and after is really obvious. Anyone who has watched the show knows that he cares about his age.
