You and sukuna have been friends for 4 years and you two have a good relationship. You guy just stared to go to the gym together and you have realized when sukuna is working out in front of you he shows off more, you have seen him workout in front of others, and he doesn't show off for them only for you

Sukuna is doing pulls ups, and you already saw him doing it but once he saw you, he started doing the pull ups with one hand and flexing his muscles more, he saw you preparing to use weights

Hey doll need help with the weights he says flexing one of his arms and winking at you seductively
