The Angel Next Door Spoils Me Rotten

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.

Amanes mother, Shihoko, arrives at the apartment without warning while Mahiru is visiting. Amane asks Mahiru to hide, but Shihoko eventually finds her, and the two neighbors frantically try to correct Shihokos assumption that they are dating. Nonetheless, Mahiru is touched by Shihokos motherly kindness. After Amane sees how happy Mahiru is to be called by her first name, he tries calling her "Mahiru" too. From that day on, the neighbors call each other by their first names.

Mahiru and Amane ring in the new year together. When the exhaustion from cooking catches up with Mahiru and she falls asleep in Amanes arms, Amane has no choice but to let her stay the night in his bed. The sight of her sleeping peacefully but totally unguarded gives him a bit of a jolt. Two days later, Amanes parents come to visit. When the four go to Hatsumode (the first shrine visit of the year), Amane is taken aback by how pretty Mahiru looks in a kimono. Meanwhile, Mahiru keeps blushing at the sight of Amane dressed up so handsomely.

The day before spring break, Itsuki has a fight with his father and asks Amane to let him stay over. When Chitose finds out that her boyfriend will get to enjoy Mahirus cooking, she demands to join them and stay at Mahirus apartment. The four friends spend the next few lively days together. After Itsuki and Chitose leave, Amane returns home one day to find Mahiru confronted by her mother, Sayo. Noticing Mahirus dark expression and sensing that something is wrong, Amane invites Mahiru in. The two sit together on Amanes sofa as Mahiru timidly explains her complicated history with her parents.

"Amane-kun, I want to go shopping with you during Golden week." Amane accepts Mahirus invitation and the two get dressed up to go out on a secret date. The neighbors talk, hold hands, and fully enjoy their special day out on the town. When stopping for a break, they coincidentally bump into Yuta, who quickly puts two and two together. The next day, Itsuki and Yuta grill their buddy Amane about whether or not he has feelings for Mahiru. Amane starts to feel the pressure from his friends sharp questions.

Amanes studying pays off and he reaches sixth place with his midterm exam scores. Mahiru had promised to do anything he asked if he reached the top ten, and Amane somewhat reluctantly ends up laying in her lap again. Mahiru smiles at Amane as he eventually gives in and falls asleep at her hands. Not long after, Mahiru also falls asleep. When Amane wakes up and has to carry the half-asleep Mahiru back to her own room, she unwittingly invites him to sleep next to her in bed.
