Forgot this BL manhua/manhwa title

I don't remember what's it about but I remember that MC got tricked by his mother, thinking his child still alive but actually dead. He knew after he accidentally met the fake child and the real mother of the child face to face. So, this time, MC mother gave his dead child ashes. And he put the ashes on a potted plant. After idk what chapter, MC saw ML's bf(?) touch or question about the potted plant and he scold the ML's bf then ML and MC got argued to the point ML throw the potted plant to the floor I think. Anyone know? ┗( T﹏T )┛
