ignores it and goes to the gym

Chun-Li: "Eew! Surely that chemical toilet will be very dirty. I have no reason to be alarmed I just ate too much, with a little exercise my old belly will deflate completely"

Chun-Li then decides to ignore the signal that her stomach had given her and after a short walk she arrives at the gym. Chun-Li wear her training outfit in the locker room and, after doing a quick warm-up, starts kicking a punching bag and doing other exercises for over half an hour.

Chun-Li: "Uff! Uff! These exercises have exhausted me, I'm all sweaty! I think I'll take a short break"

She grabs a towel to wipe away the sweat and sits on a gym bench drinking a bottle of water to rehydrate. However at that moment she feels that something is wrong with her stomach.

Chun-Li: "Ggggggrrrrwwwllll"

Chun-Li: "Oh strange, my stomach is gurgling"

Chun-Li: "Gggggggggrrrrrrwwwwllllll"

Chun-Li hold her stomach: "Oh God I feel a strange pressure, like a lot of gas is growing in my belly!!"

Chun-Li tries to rub her belly with one hand to relieve the pressure, but it doesn't seem to work

Chun-Li: "Urgh! Maybe if I release some gas the pressure in the belly should decrease"

Chun-Li looks around, unfortunately the gym is full of people

Chun-Li: "I have no other choice, let's just hope it won't be too loud"
