According to Oddity Central, both of them intentionally sleep and stay in houses and apartments that are considered haunted. This is done in order to dispel the haunted house issue so that many people are interested in buying them. Agents sometimes find it difficult to sell houses with a bad past record, such as the death of its occupants.

These two students went viral and even appeared in several publications of Thai news agencies, such as The Nation. At that time, they had just started promoting their services through social media and had not yet acquired any clients. However, Cheng was confident that there was a market for certified ghost-free houses.

"I also received similar jobs, such as staying overnight at cemeteries or other haunted places," he said. As for Boonprakhong, this student is actually afraid of ghosts. However, for him, this job will help him prove to himself that ghosts do not exist. On the other hand, he will certainly also earn an income."
