Coffee

 "You're right! Damn, this tastes so good!" Evan said from his best friends body. Evan always hated coffee but not Ling. She loves coffee and can't go on the day without it.
When Ling discovers her new swapping ability, she wanted to test it with her best friend, someone she can trust. And to further explore the effect of the swap, Evan in Ling's body now can enjoy the coffee just like Ling used to.

However, now Ling in Evan's body has a strong reaction of the coffee.
"Wanna try? This is really good!" Evan said as he offer Ling the coffee mug.
"Uh no- I never felt this disgusted by the scent of the coffee alone. You really hate coffee, didn't you?" Ling said as she tried to avoid while fanning her surrounding. Evan was giggling looking at the reaction his best friend had.
