Yu and his friends try to find ways to help Marie retain her memories. Inspired by a TV quiz show, Teddie comes up with the idea of hosting a special quiz show! Will it help Marie remember her memories?
Aren't I lonely,
walking on alone, you ask?
قد تتساءل، ألا أشعر بالوحدة وأنا مسافر بمفردي؟
Bin ich nicht einsam,
alleine laufend, fragst du mich?
¿Que si me siento solitaria 
porque camino sola?
¿Que si me siento sola 
porque camino sola?
Je marche en solitaire.
Se eu não me sinto triste andando sozinho?
