Why does a drama of two men become the biggest dark horse this year?

Because poverty and perfunctory are two different things, even if the crew is poor and there is no traffic to join, there is basically no such drama before the broadcast, but the crew and the actor teacher have made efforts, whether it is empty mirrors, costumes, adaptation of the script, or the wonderful performance of the actor teacher, everyone can feel it unintentionally and everyone can see it.
