"Brother, are we really taking a bath together?" 
 
And so, a forbidden bathing experience began. Me, my sister, and childhood friend—one man and two women—are sharing one bath. After involuntarily "overflowing," the sister's secret love come out?! 
 
This is a young romantic comedy that won't let you say, "it's over!"
