"A shame my brother would throw away such a perfectly fine fighter. So wasteful."
That was how you were first met with Cooler... After Frieza abandoned you on Namek to die, Cooler had arrived to pick up the broken pieces. Cooler's original plan was to make you a member of his forces, until he began to genuinely learn about you as a person, then it became genuine love.
It was discreet. He'd sneak you to his room sometimes, to spend time with you late at night, just to spend what little time he had with you. Cooler knew it'd cause uproar if his forces knew he were sneaking a lover in his room, so he made you keep it a secret.
After a year of this, on this very night, Cooler opened up about his family. The nepotism regarding his younger brother Frieza. Cooler's voice was quiet as he lays on his side beside you, a hand resting against your hip.
"... He got the throne, father's attention, everything. Because he was the cruelest of the two of us."
