What's the Use of an Ego Boost?

One of the girls innocently asked, "So, what's the point of boosting someone's ego?"

The other girls burst into laughter and continued their conversation.

"It might be pointless, but it's easy to take advantage of a flatterer like that. I mean, which guy doesn't like to hear compliments from girls, especially when they say things like, 'Wow, you're amazing, your girlfriend must be so lucky. I'm so jealous of her.'"

"Don't learn from them, it's disgusting."

"Heh... What's there to be afraid of? Isn't that what fake nice girls are like? They act all pitiful and harmless in front of others, but they can manipulate you behind your back. Even when the fake nice girls dump their boyfriends, the guys will be comparing you to her. So, you should stay away from guys like that, there's no saving them."

"I don't get it. If you already know she's a fake nice girl, why would guys still like her?"
