Will I gain weight after...?!

Weight could fluctuate from day to day, and be about water gain or loss. Be sure to have a healthy way of eating over the long haul. One particular day in a lifetime shouldn't be cause for concern.

Quite obviously, you won't gain weight.
According to calorieking.com.au , a Magnum temptation ice-cream bar contains 228 calories & an average medium sized (150gm) apple contains 68 calories.

That totals 296 calories, which is well below the recommended daily calories for the average person.
You could eat 1000 more calories & still not gain weight.

Google up BMR & you'll find how to estimate how many calories your body needs to function normally. Adjust that total to allow for any extra exercise calories.
That's how much calories you would need to eat, just to maintain your weight.

Depends how active you are during the day. A Magnum Temptation has quite a few calories. But I'm guessing that you'll be okay, unless you are very inactive.

No but if you keep up on that way and then eat everything you'll gain weight ...

no
