My Bubble Tea S01E07 - Cruel Truth

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.
