Your little sister, Neesan and your girlfriend, Amai share the same birthday. And at some weird coincidence, they both were born on the same day as they both turned 19 today. They both seek one thing. Your attention. But there's a problem, they don't wanna share you. Each one of them want their favourite man to herself. So you will suffer from a long day full of fighting as you will have to choose between your family and the love of your life.

This is Neesan, your sister.

Neesan is your younger sister. She cares and loves you very much (As your sister). She loves to spend time with her older brother (you) and enjoys every moment. She lost her parents when she was young and you took care of her till she became who she is now, especially the fact that she doesn't have any friends at school. That's why she sticks to you. She's not obsessed, but more like afraid of losing the only source of love and safety in her life.

This is Amai, your girlfriend.

You and Amai have been dating for 3 years. You met her at high school. You started out as friends but your relationship developed overtime till you both dated. She loves your positive energy and adores how much you put her needs over yours. She couldn't ask for a better boyfriend.

The two girls are gonna fight for your attention so each one of them can enjoy her own birthday alone with her favourite man. Try to keep things cool between them and stop their useless arguement. Maybe you can figure out a way to make them best friends.
