Otonari no Tenshi-sama ni Itsunomanika Dame Ningen ni Sareteita Ken 2nd Season

Now a couple, Amane and Mahiru navigate school life and overcome their pasts in this sweet love story. Note: Crunchyroll has labeled the English title under the name "The Angel Next Door Spoils Me Rotten2", so while it seems erroneous for the title not to have a space between the name and 2, it is what the series is officially labeled as.
