A silly and almost innocent happiness.
Liu Wei had everything she needed to win that match, all she needed was to hit her shot.
The position wasn't the best and she definitely didn't feel confident, but everyone was rooting for her in one way or another.
Of course, no one wants to lose that bet.
But the bet just creates some fun and fuels the competition. At the end of the night, everyone will be happy after a pleasant afternoon with the family.
The bet is also just a detail, after a certain point in all that, some things don't matter as much as seeing someone else's happiness.
Hong Bo was excited with her mother, the two didn't want to lose, but the match had been really close.
They did their best to be able to compete somehow and Liu Wei not knowing how to play helped them a lot in that, so focus on doing your best and with some luck you can get something.
