"Buyer's Remorse" by Daniel Caesar (ft. Omar Apollo) is a song about regretting a decision that was made too quickly. The song is likely about a relationship that Daniel Caesar entered into, thinking it was what he wanted, only to realize that it wasn't what he expected.
The first verse sets up the situation. Caesar got what he "prayed for" - presumably a relationship with the person he's addressing in the song. But now that they're in bed together, he's having second thoughts. He acknowledges that they "look good on paper" - i.e., they might seem like a good match in theory, but in practice, things aren't so simple.
The pre-chorus and chorus illustrate his feelings more clearly. Caesar feels like this person thinks they have him "wrapped around their fingers", and he's frustrated with himself for letting that happen. He wonders what's "behind those cold dead eyes", suggesting that he feels like there might be more going on with this person than he initially thought. The chorus is the most direct part of the song - Caesar is suggesting that they should just have sex ("lay you down"), but he's hedging his bets by saying "was it my fault?" and "hop out, bitch". He seems to be implying that this person is unreliable or untrustworthy, which have caused him to have second thoughts.
The second verse is a bit more introspective. Caesar acknowledges that he got what he "prayed for", but it's not what he "slaved for". In other words, he worked hard to get to this point, but it's not living up to his expectations. He reiterates that he feels like this person thinks they have him "wrapped around their fingers".
The song ends with a short outro from Omar Apollo, who sings "I wouldn't change / Oh, I wouldn't dare to change / How I feel about you / How I feel about it". This could suggest that despite Caesar's mixed feelings, Apollo is more confident in his own feelings about this person and this relationship.
Overall, "Buyer's Remorse" is a song about regret and second-guessing. Daniel Caesar seems to be questioning whether he made the right choice in getting into a relationship with this person, and he's frustrated with himself for feeling like he's not in control of the situation.
