no joke guys, when you show people you care about them they'll just show love back, we always have this weird feeling to care about other people but receive nothing back but that happens because you don't make it explicit, you have actually to open your mouth and talk to prove you are a nice person, it doesn't matter how good you are if all you have are just good intentions and zero actions, be more open and talk to people, becaus being very nice but an introvert with an anger face won't help.
