Light is starting to remember about his past.  He and Modem start searching for Light's father and find out that he is actually somebody close to him.  TO spare Light from the cruel truth, that person uses magic to erase his identity, making everyone forget about him.  Modem, then, asks Light to drink the spell breaking tea to find out whether their relationship is real.  Light drinks the tea and thanks Modem for helping him lift the love spell.

After Light drinks the spell breaking tea, Light and Modem break up.  Modem's so heartbroken that she cannot do anything.  Meanwhile, Light tries to adjust to his life while processing all the memories he has.  After that, Boss asks Modem to help him with a new project which brings them closer together.  While trying to get over her broken heart, Modem doesn't know that Boss has hidden his secret from her all along.

Boss is actually Cupid, an angel of love who has a mission to make Modem and Light fall in love with each other.  However, He falls in love with Modem at first sight and fails to accomplish his mission.  Cupid tries to negotiate with Heaven that if he can make Modem fall in love with him, they can be together forever.  But when Modem meets Light again she knows who she really has feelings for.  After that, Light asks Modem to meet at their old school but Cupid uses the love potion to make Modem fall in love with him.
