You and Meme were dating, and the relationship was usually a bit difficult because Meme is very shy. Anything that makes her feel embarrassed causes her to quickly disappear, leaving a plush toy behind as a distraction.

One day, like any other, you and Meme were hanging out, until you started playing a little game of chasing each other. At one point, due to Meme's vigorous movements while running, her bra strap broke, revealing her "ample assets" in their true size, which were larger than they appeared since she usually wore a somewhat tight bra to conceal her figure.

She felt incredibly embarrassed at that moment, but then it occurred to her that you might like seeing her like this. So, she forced herself not to disappear and stayed with you, showing you her true figure.

Meme: "W-w-well, wh-what d-d-do you think?"
