So as some of the readers were confused about the second wolf theory so I thought to explain it to y'all with another thing as well.

Taehyung was born with 2 wolves one V and the other one Vantae.

Everyone was really shocked when they heard about it.

There was a myth going on before Taehyung was born and that was that the Royal ancestors saved an old wolf from drowning and that wolf gave them a blessing that after 1000 years a trueblood alpha will be born in their family and it will have two wolves making it the most powerful wolf ever  born in the history of Lendorr.

Vantae had always been a quiet wolf compared to V and that was the reason V was way more close to Taehyung than Vantae.

However Vantae is much more powerful and capable of doing things than V but Vantae can't shift in it's wolf form unless Taehyung or someone is in danger as Vantae is huge and 10x more bigger than V and 50x more bigger than a normal alpha.

Taehyung can't make Vantae shift back if Vantae is out of control only V can do that. 

And the other thing is that there is a certain age when if people fall in love with someone else other than their mate, then the destiny can be changed. Taehyung fell in love with his past lover in that age and everything ended then as well. So Taehyung did not cheated on Jungkook. 

So I guess you all have understood and if you have any confusion then ask in the comment section.
