On the left we have the nice side,ofcourse! ^^. Nice, gentle, caring,happy. Be nice with him and you'll get assured with a nice and lasting friendship
On the right we have Shadow DV, a side nobody would want to wake up... Only wakes up if the nice side has been backstabbed by a strong friendship or simply hurtful lies. Many unexpected things , nice or bad,may come out from Shadow DV if it's been provoked.
Yep,this is based off the "Shadow Self" from Persona 4, but you get the idea,right?..
