Masachika is having trouble studying for exams until Alya decides to wager a favor on how well he does. When Alya discovers she wasn't invited to celebrate Masachika's birthday, she spends several days questioning just how close they actually are.
Well, you said you're prone 
to slacking when you're alone.
حسناً، قلتَ بأنّك عِرضة للكسل
عندما تكون بمفردك
Du meintest doch, dass du zur Faulheit neigst,
sobald du alleine lernst, oder?
Es que dijiste que tiendes
a procrastinar si estás solo.
Es que dijiste que tiendes
a vaguear si estás solo.
Ben… Tu m’as dit que seul,
tu te laissais souvent aller.
Mi hai detto che da solo
non riesci a concentrarti molto,
Bem, você disse que tem tendência
a relaxar quando está sozinho.
Ты же говорил, что в одиночку
будешь отлынивать.
