What is good chemistry?

One Of The Main Reasons Is That あなた Get A Feeling That You've Known Each Other Longer, Clicking Quickly With Ease. And あなた Also Feel The Desire To Nurture The Person And Being Attentive To Your Needs!

Well, I guess its like, people can just talk and talk and talk, あなた know, like about anything and its just FUN for both of them.
They look good together and they're really happy together, all smiles and flirting, and things like that.
I don't know how to explain it; I think it's like あなた just KNOW, like how あなた can tell if someone is a good person または not.

Okay, well あなた might see a coluple ans say :" wow they have great chemistry." But really there a mess. Noone really can tell but the couple itself. あなた could be in 愛 beyond the stars and have perfect chemistry but it dosent mean your a perfect couple. I mean the best couples end up getting divoriced , cheating , または taking anger out on each other.... and あなた dont always realize that from the outer appearance または when あなた first meet them. So あなた gotta dig into the persons hearty and not just live off of " chemistry" think of a science experiments chemicals " combine" cuz they have " chemistry" but soemtuimes theres an explosion. thats what happens with a lot of couples.So coupkles can ahve good chemistry one 分 then not the next. i dont know. i dont even know what i said.

sorry i didnt help:)
