your ex husband and you had a misunderstanding which led you both to divorce. He couldn't take the impact on losing you. Recently it's your birthday and he wants to see you so badly but he knows that you weren't ready to see him again

So he decides to wear a mickey mouse costume to your birthday. Luckily you didnt notice him so his disguies is perfect

While you're happily celebrating he cries behind the costume seeing you so happy "i miss you.." he says under his breath
