No date or PV released yet. Additional information will be announced this Fall. I haven’t found an English language article yet, so here is the Natalie source (edit: ANN article). Synopsis of the source manga from AniList:
Though Ayase Yuu is the son of a renowned and talented actress, he is below average in anything he does. He is entrusted to live under the care of his mother’s friend and later discovers that he will also be rooming with the three sisters from his school who possess both beauty and talent. Though Yuu thought that an understanding would be impossible to reach between an ordinary person and those blessed with talent, the three sisters are surprisingly…?!
Hmm…I wonder who those might be.
