From Aerandria Scans:

Haruka-kun is the tall, strong and athletic newcomer at Yakugan temple, a place strictly off-limits for women. That, however, doesn't seem to be a problem for the newcomer, especially after it becomes apparent that Haruka-kun is attracted to the chief priest who is not averse to Haruka-kun himself. Is a boys-love relationship Haruka's great secret? Or is it something completely different? Find out in this temple-based love comedy series!
