Please explain this weird bitcoin transaction

I’m an EVM blockchain engineer and I began studying Bitcoin few days in the past.
that is my good friend's tackle of bitcoin pockets: bc1pfatr7dvkz65y6p6xxv84anesttxc7q9etez8em5uyvll5kk8atpqrx3r2s

and what makes me confused is a transaction in his historical past. https://mempool.house/tackle/bc1pfatr7dvkz65y6p6xxv84anesttxc7q9etez8em5uyvll5kk8atpqrx3r2s

the very first transaction is comprehensible.
there was no transactions earlier than first transaction and bc1q7pcfjas8swacpwnmm5d4s679jffn3lawkm89kv despatched some quantity of BTC to this pockets. (It's okay)

however the subsequent transaction is unusual.
