I just really don't know how it works
The only way that works is if the girl likes you already, if she doesn’t like you she won’t care.
You either want someone or you don't, if you do then you need to put in effort.
I'm not sure who gave you that advice but they clearly have no experience when it comes to relationships.
But if they have shown interest then no. I feel like so many guys are immature and don't put effort in to be cool or "one of the lads". If you like someone you shouldn't care.
