Hip hop artist OVAN responds to malicious DM about his dog

On March 7, Hip hop artist OVAN took to Instastory to call out one of the malicious DM's he had received. 

On his Instagram Story, he shared a screenshot of one of the direct messages he received in response to his single "I Need You" beating out BTS' s "ON", IU's "I Can Hear Your Heart", and Zico's "Anysong", and more to hit number one on Genie. 

The DM was a reply to his dogs' picture on his Instastory, and that person copied and pasted a Bosintang recipe.

On the screenshot, OVAN wrote, "I'm not a thief. But just because I didn't prove that I'm not a thief, my friends and family, my dogs, people around me, my belief- my everything is being mocked. I have been explaining 'sajaegi' accusation for the past 2 years and I was able to sue most of the accusations for libel. I can't explain this to every single one of you. Some of you know but you wouldn't stop hating me anyway. I'm so hurt and sad. I really don't know what to do. I didn't want this rank. Please help me." 

Netizens disapproved of this DM for crossing the line, but they are still suspecting chart manipulation. What are your thoughts?
