Love is an illusion. So it differs depending on the person. It can be powerful enough to become real, and fragile enough to shatter at any moment. That is the power of illusion!!! Hmm, my answer maybe too anime.
Love is a chemical reaction in your brain to socialize with others, so if you block yourself fully from others and addictively rely only on materials to fill the void in you, The hole will continue to get larger and larger, Till you become a NEET.
Love is when pheromones make you agitated (insert Lenny face) and you start to lust after a person. After you lust after someone, you start imagining how nice it would be to do ecchi things to them. When you start dreaming of a future together, you start imagining them doing all the chores for you or earning you money while you stay at home. Naturally you are still feeling ecchi for them. If and when you do the ecchi together and experience the SUCC or THICC, you try to get into a relationship to do it more frequently. If you have that relationship... Well this is just about love so I'll leave it there Tl;Dr ( ͡° ͜ʖ ͡°)
Love for me(not us) is a phenomenon. Whether it is a blessing or a curse depends on the one who loves, and the one who is loved.
I'm a little bit late, so here's my take on love. Good luck. Find someone to consult who's experienced it. Learn from their mistakes. Don't abuse the kids. Remember anniversaries. Don't lose all the money. Die with someone at your funeral.
Most of the people here are talking about love in relation to the idea of a partner...Love is an emotion of caring when you want to best for the people you love...Love can include parents love, friends love, sibling's love...there are varieties of loves...Love is an emotion to express that you care, I guess? it's just a word to describe something we truly don't understand, after all.
