One day, he suddenly shows up at the Forger residence. The Forgers, who are full of secrets, and Yuri, who has a secret identity, come face to face!
They hide what they're truly feeling 
through fake smiles or bravado,
يُخفي ما يشعر به فعلاً خلف
،الابتسامات الزّائفة والتّظاهر
Sie setzen ein Lächeln auf
und spielen anderen etwas vor,
Ocultan sus intenciones
bajo una sonrisa,
Ocultan sus intenciones
bajo una sonrisa,
De faux sourires
cachent nos intentions et notre nature.
celano ciò che pensano davvero 
attraverso finti sorrisi o spacconate,
Escondem seus sentimentos atrás
 de sorrisos falsos e mentiras,
За лживыми улыбками
они скрывают своё настоящее «я».
