The story of 00s that started with sadness and ended with laughter

Starting with a comparison of Eric to a salmon swimming upstream,

Eric's counter-argument that if the water goes down the drain, maybe living like a salmon is the right thing to do is so typical of him lol.
There was even a remark that being under a lot of stress makes you feel like an ocean sunfish, and while everyone laughed, the atmosphere was one of somewhat agreeing.

The disappointment Sunwoo mentioned was Eric taking off his shirt during the concert, but he is not the type to get upset easily.

They said that day was so hectic that they even got the lyrics confused, so they suggested putting on and taking off the top beforehand.
Conversely, Eric says there are about 157 things he was upset about with Sunwoo and asks him to pick just one, but that very statement is upsetting.
