It’s hard to find words to explain why you love someone, they don’t make words with that much passion. And even if they did, there isn’t a perfect combination of syllables and sounds to create a word strong enough to explain love. Love is just a filler word, a useless word that tries to do a job that no word can.
How love works: Proximity leads to intimacy, and intimacy leads to a relationship. In other words, people who are around each other a lot, get close, and end up hooking up. So it's no great mystery why bosses and secretaries or co-workers or classmates end up dating each other.
