When I was in college, a boy had a crush on my friend for a long time, but he never dared to confess.

On my friend's birthday, the boy sent a bunch of red roses to my friend. After receiving the flowers, my friend thought that the boy might like him, so he invited the boy to spend his birthday together that night.

After receiving the invitation from his friend, the boy finally got the confidence and felt that his friend liked him, so he confessed to his friend that night and asked him if he would like to be his girlfriend. In this way, the two established a love relationship.

So it's not a confession for boys to send girls red roses. Red roses represent love. Sending red roses can only show that boys like girls, but it is not a real confession. A true confession must have real meaning, such as I like you and want to be with you. I love you; I want to take care of you all my life and so on.
