Explanation:
if a person find a person she/he can trust the most makes her Happy, because trust and love is the key for long lasting happiness I'm not saying
find a lover my point is if the person feels that He/she is important that's the Happiness because they know you're Value,one of Best example is Family, and True Friends having them is the most happiest part, Through Actions we can express our love and happiness by hugging them giving them gifts protecting them, Happiness is when everyone knows you're Values and know how can they Valued you and you know their Values too.. Because for me Happiness starts in Trust turn into Love that leads you too True and long lasting happiness.
that's base on my own opinion☺️
