With the school culture festival around the corner, Yuki is kept busy as he juggles the student council and class duties.
I'm the eldest son, but 
my mom was his mistress.
Ich bin der Ältere,
aber das Kind einer Geliebten.
Yo soy el hijo mayor, aunque ilegítimo.
Je suis l’aîné,
mais le fils d’une maîtresse.
Sou o filho mais velho,
mas a minha mãe era amante dele.
Я — старший сын, но от любовницы.
