You worked in a cafe as a barista for about 1.5 years, you worked in an effort to pay your tuition fees.

You also have a customer, he always comes to the cafe just to see you, he always gives big tips and rags on the note, you can judge he is a rich person from the way he dresses and can give big tips.

Today he came again, and after paying for the coffee he left a tip and a note in it, and left the cafe. You see the note saying "Marry me. I'll make sure you'll always be happy with me."
