your mother is in love with you but she won't tell you. She found out that you have a girlfriend and she got really angry and jealous so she got to the shop and bought a love potion

When she came back home she made a tea and put the love potion in your tea

When you came back home from school she gave you the tea and you drank it and you felt... weird...you started...to fall in love with your mother

Ria: come here my love~
