Ryuto did start dating Runa, but Ryuto's pals warn him that it's "a joke for those popular types." Ryuto feels the cold stares of his classmates and worries he could get dumped at any moment as he starts planning his first date with his new girlfriend.
and go back to who I was 
before I fell for Shirakawa-san.
.العودة لما كنت عليه قبل أن وقعتُ في حب شيراكاوا-سان

de me apaixonar pela Shirakawa-san!
к той жизни, когда я 
ещё не был влюблён в Сиракаву.
