Was Natsuki's first love, Atri? His beautiful childhood memories are gradually being overwritten. Despite his unwillingness to admit it was her the facts around him are lining up to force him to, but he continues to deny it. 
It would make you happier 
if I had a heart, right?
سيُسعدك إذا كنتُ أملك قلباً، صحيح؟
Und dass ich mit
so einem glücklicher wäre?
Preferirías que tuviera corazón.
Preferirías que tuviera corazón.
et cette perspective te réjouit,
si je comprends ?
Saresti più felice se ne avessi una, no?
Eu ter um coração vai
te deixar mais feliz, não é?
Вам будет радостнее считать,
что у меня есть душа.
