Vintner's Harvest Bergamais. Sounds good. Beaujolais style, should be good to drink fairly young especially when sweetened. And the kit probably doesn't matter in this case, but I'd like everyone to get in the habit of being specific when asking about kits, because sometimes it matters. (EG Winexpert Riesling only narrows the field down to 5 or 6 (guessing) possible kits.)
Sweetening when two people want different results...Bottle the batch with sufficient sweetener for the least sweetness (in this case semi-sweet for your friend). Then the person (you) who wants it sweeter can add a small amount of sweetener to their glass.
