We have to find the true culprit

Minho texted Hoseong and told him the location. Hoseong was walking next to Baek Eun and he was swallowing his saliva strollingly. He inquired, 'Is his soul no longer disturbing Hea from now on?

Baek looked at him and responded, 'I have only been able to trap his soul for two months. After two months, he will be released from the cage that I have created with the protective stone. After two months the moon will start its full circle again and he will be able to regain his energies'.

Hoseong's feet halted on the way and he pronounced, 'Are you saying we haven't gotten rid of him completely? Baek sighed and answered, 'No, we cannot get rid of him entirely until we find his real killer who killed him. His murderer must confess his sin in front of him and be guilty of his act towards him. We cannot bury his body until his real culprit presents himself and accepts his sin and passes through the process of a sinful act!
