Only btc 0.00621581 were effectively received by B (recipient)?
The amount come back to A (btc 1.55200322) was not sent to B at all?
Therefore, can A say "I paid B with btc amount 1.55821903" in any ways?
Many thanks to the community

No.
A used a 1.55824169 BTC "coin" but sent themselves change in the form of a 1.55200322 BTC "coin". B only ever received a 0.00621581 BTC "coin" and nothing else. B never had any control over the amount of change.
At no time did B have any control over the 1.55824169 BTC "coin".
At no time was there ever any  1.55821903 BTC "coin". That amount is just the sum of the two "coins" created in this transaction.
The difference between 1.55824169 BTC and 1.55821903 BTC is the fee amount that a miner will include in the coinbase "coin" that they create. The face value of the coinbase "coin" will be a larger amount because it typically includes other fees from other transactions in the same block and a mining reward for the block of transactions.
