So basically, reason for bonding is lowering the energy?

Last orbit has high energy, and when bonded has lower? Makes sense.

But how does this look, this bond? Do electrons go around both nuclei or something else?
Yes, the energy of two bonded atoms is lower than the energy of two separate atoms. That's the definition of a bond.
How it looks is a more difficult question as it is an essentially quantum mechanical effect.
But it's certainly true that the electrons ramble around both atoms.
