Shackles and Sparks

The brother of a talented painter who is docile on the surface but is actually yandere x the brother of a business elite who is cold on the outside but hot on the inside but restrained in his restraint, a forbidden love that begins with the shackles of blood and ends with the redemption of the soul. When the DNA test report revealed twenty years of lies, all the "shouldn't" throbs became the cruelest joke of fate - it turns out that we have never been bound by blood, but have long been imprisoned by love.
