Why butterfly mariies snail

[stevenmai]

Bee really likes Butterfly. Butterfly married a snail before Bee is intending to propose to her.
Bee is heart-broken, he asks her for the reason of choosing snail instead of him.
Butterfly answers : "At least he owns a house, not like you, living in a dorm with tons of roommate."
