An example is Me, anytime I ask how it feels life, they always tell me about butterflies in the stomach and heart beating I understand none of that my foolish question is always like how can you get butterflies in your stomach when you never held them in your hands or even know how they’re like lol I love seeing people in love though

From my observations, ppl would appear more panicked in certain moments; most likely conscious of the other person. They would behave a bit distracted as though their head is blank/occupied. They would often lose focus on the task at hand. As for the appearance, they may blush, they may appear stiff/forced, and their eyes may also shift more frequently.
Emotionaly tho... I assume nervousness, panic, anxiety, and a certain happiness? Not much info personally; only heard from others.
Even tho ik these info about some love behaviours. I've never truly felt it. There r cases where I think I felt it for a bit, but I can never truly get a grasp on it. The more I think about it, the more I think I lose that feeling. I assume that it is a subconscious thing that needs to flow naturally in order to grow. Once u try analyzing an emotion with yourself as a subject, it becomes difficult to understand since u become too distracted on understanding the feeling instead of experiencing the feeling during that moment.
I rambled. Im sorry... but yea- it's... difficult to become conscious of this feeling until its presence is strong enough for it to remain (I assume).
Damn she is a modern person why does she not realise it yet but still i love her
