You ask him why it's so hard to trust a woman. Because he's never truly been loved.

A man who has been loved will realize that the finger he uses to unlock his phone was taken by his girlfriend to open her online banking.
When she recorded it, she would even complain that his fingerprint was too shallow, unable to unlock, and ask him to use the other hand.
He thought women checking his phone was out of suspicion. Actually, he didn't know that once a woman genuinely accepts you, the phone password is your birthday, the payment password is your birthday, and she even remembers the date of your last period in her notes.
She wasn't checking his phone for surveillance. She was lying on his lap, using her fingerprint to unlock it, searching for food delivery red envelopes.
Meanwhile, he's sweating on the side, not thinking about the red envelopes, but about the chat history that hasn't been fully deleted.
She actually saw everything a long time ago. She didn't say anything, but wrote a line in the red envelope note: "This store is super sweet, don't order from here anymore."
He has never been loved. So when she was just searching for red envelopes on his phone, he was thinking about how to explain to his ex about the milk tea he ordered.
