Amane Fujimiya is a socially awkward first-year high school student who lives by himself in an apartment. His neighbor is schoolmate Mahiru Shiina, a girl who is so beautiful and so unreachable that the other students call her an "angel." On the way home one day, Amane notices Mahiru sitting alone on a park swing, drenched in the rain, so he lends her his umbrella. When Amane catches a cold the next day, Mahiru insists on taking care of him, and the two next-door strangers embark on an unusual new relationship.
This is how the angel and I began 
our unusual next-door relationship.
هكذا بدأنا أنا والملاك علاقة الجوار غير المألوفة
Und so begann die kuriose Nachbarschafts-
beziehung zwischen mir und dem Engel.
Así es como el ángel y yo comenzamos
nuestra extraña relación de vecinos.
Así es como el ángel y yo comenzamos
nuestra extraña relación de vecinos.
C’est ainsi
E così ebbe inizio la mia strana relazione
con l'angelo della porta accanto.
Foi assim que o anjo e eu começamos nosso
relacionamento incomum como vizinhos.
Так и начались мои странные
соседские отношения с ангелом.
