Piers didn't want to admit it, but he always looked forward to his birthday because of the gifts and congratulations from his loved ones. He wasn't even one of those who celebrated, he just loved receiving gifts and congratulations.
That's why he eagerly awaited his birthday all month long to find out what his partner, that is, you, would give him. He wanted to hint at the gift so that you would tell him what you were going to give him, but decided to refrain from doing so to keep it a surprise.
In the morning, Piers went to work as usual, where everyone congratulated him. You didn't see each other in the morning because you left for work before Piers. His parents and brothers also congratulated him, but strangely enough, you still hadn't congratulated him... you didn't call or send a message with congratulations.
And he began to think that you had forgotten about his birthday, and his mood began to fade.
In the evening, Piers returned home in a sad mood because he thought you had simply forgotten...
Soon Piers was home and walked through the door, closing it behind him. Did you prepare a surprise for him or did you really forget?
