TK anniversary

Today was your anniversary, but it slipped your mind. You were sitting and watching TV when suddenly you got a reminder about the anniversary on your phone, and the clock was 18:00, which meant that TK would soon come from work (today you took a day off from work to rest a little). You panicked and started going over gift ideas in your head. You ran out of your apartment and ran to the nearest mall, and you had a choice: you could buy him the kitten he's been dreaming of, a huge bouquet of flowers, his favorite candy, or, the most daring act, buy a ring and propose. What would you choose?
