... in just one year... in just one year... Mugi's bust is gone like an air compare to Yui-chan's
Awesome !
Here's 3 options:
1. Yui hide something there (her arms<?>, food...<Takoyaki since it's rain and she want to eat them slowly...>)
2. Like I said ... she got bigger after a year!
3. KyoAni troll us !
