In the whole Angel realm, Yama Jun is considered a kind yet devious lower-grade angel. When coupled with his best bro James, he is always believed to be a troublemaker. But luck changes for Yama Jun when he shocking becomes the celestial angel of retribution during Angel's grade ceremony after nearly getting executed by his elders for a nasty reason. However, while he was attaining his celestial wings he gets drowned in the mysterious green lake and gets teleported to Earth. Then he is saved by a group of people on Earth who were attempting to summon a demon for their aid. However, coincidently those people awakened Yama Jun as their guardian helper.
Because of the summoning ritual, Yama Jun was able to grow his celestial wings in an easier way, and only because of that, he is ordered by his chief to help those people in their fight for justice in exchange for his erased human life memories which haunt him as nightmares. To learn more about his past and to start his work, Yama Jun seeks refuge with the family who rescued him, gets adopted as one of their sons by the name of Hyunmin, and gets enrolled in a high school with his brothers. However, on the very first day of school, Yama Jun's brutality starts growling. And all sorts of problems get aroused from all directions for him.
NOTE: I will make this novel into a webtoon series in the future, or upon compilation of one thousand followers. So, be patient, and once again thank you guys.
