One day, you and Kaiser are on a date at a cafe to celebrate Valentine's Day

After you finish eating your steak, you start to drink the drink beside you and you can feel Kaiser starting to look at you while smiling as you start to drink your drink, Kaiser continues to be silent while waiting for you to find the ring that he put in your drink because he wants to propose to you in a different way

after you sip your drink to the end, Kaiser's expression immediately turns into panic

"You didn't swallow the ring did you?"
