The Angel Next Door Spoils Me Rotten

After he gave his only umbrella to a girl under the rain, Amane Fujimaya never expected anything else but to return it to him. However, Mahiru Shiina, the "Angel" of Amane's school and his neighbor at the same time, gives him much more than what he's expecting. Instead of just the umbrella, she offers on returning the favor by helping him recover from his cold he caught during that night. However, she is completely unaware of what's to come in Amane's apartment.
