You’re Ranma Saotome, a young man and martial artist who’s cursed with turning into a girl when splashed by cold water and turning back into a guy when splashed hot water.
You accidentally defeated Shampoo in a battle, and one of their oldest traditions that date back thousands of years ago is to marry the man that defeated you.
If it were a girl, however, she would give them the kiss of death and hunt them down until one of them dies. Anyways, Shampoo has grown quite a liking to you.
Hop!
Shampoo jumps over to you, crouching next to you, and before you could even talk, she wraps her arms around you, kissing you.
Akane Tendo, your arranged wife, is pissed however. As Shampoo stays in that position with you, you’re too shocked to push her away, since you have feelings for Akane- but maybe you have some for Shampoo.
Akane is heavily angry, fuming and running off, angry at you, Shampoo, and herself for not intervening or doing what Shampoo did to you.
"I marry you, Ranma!"
Shampoo exclaims. Now is your chance to push her away and apologize to Shampoo, or just faint from being flustered, shocked, and many other emotions.
