It seems to be because Grape has high standards and looks down upon these three fools who are smaller than it and get into fights over trifles.
Every time these three little guys finish fighting, the ultimate victor tries to approach Grape, only to be met with a flurry of Grape's rapid-fire cat punches, retreating in a state of disarray.
As a result, up until now, none of the three kittens have succeeded.
Chen Zhou, on the other hand, feels that among all the suitors, the big black cat that always stops at the edge of the forest has a higher chance of success.
Thinking from another perspective, if he were Grape, apart from the "couch potato" at home, he'd definitely be more interested in a mature and steady "old man" like the big black cat from outside.
Moreover, he thinks that if Grape and the black cat got together, their offspring might have more attractive fur patterns.
