The video likely worked due to the inherent cuteness and novelty of monkeys, especially when dressed in human-like clothing, eliciting an emotional response from viewers.
Summary
The video shows two capuchin monkeys cuddling and interacting on a bed. One monkey is wearing a pink shirt and pink pants with flamingos on them. The other monkey is nestled behind it. A person's face is visible in the background.
