Original title: ハプニングLOVE!!
This is the debut work for Tsumiki Soft. Due to their parent’s transfer abroad for work, Shun returned with his younger sister Miku to live in their hometown. The town had changed slightly from what he had remembered. He reunited with his energetic childhood friend Haruka, and met Sanae, the smart and beautiful granddaughter of the school chairman, and the mischievous and voluptuous senpai Misaki. The days he spends with them shouldn’t be that unusual, but since they are overly unskilled at love, they are lively and full of exciting happenings.
