From Megchan's Scanlations:

When your father is a Buddhist priest and your home is a temple, life can be complicated. For Satoru, Hikari, and Ogami, the thought of who will inherit the temple and take over when their father gets old is always in the back of their minds, especially when it comes to matters of the heart. Because Hikari loves the temple so much, it's been all but decided that when she grows up, she'll marry someone who can take over from her father, but when she falls for someone completely unsuitable, all three sisters find themselves re-examining their assumptions.
