Answer:
In his book, Trevor Noah reveals that he wasn't particularly popular in school. He didn't care much about Valentine's day but his friends pressured him to participate in the activities because everyone was doing it. And so, he did, he asked a girl out to be his Valentine and she accepted. However, she dumped him on the actual Valentine's day because she was asked out by a more popular guy from school.
Nowadays, Noah pokes fun at the event and even takes himself out on a date, saying 'Treat yourself.'
