Maybe a touch of punk?

All you want is for Yutong to have a good time. And, looking at the different syrup buttons, the PUNK button calls to you. Who knows how to party better than a punk?

Deciding a little anarchy is just what Yu needs, you brew up a special drink that ought to loosen up your straight-laced friend.

Purity: 15%

You switch scope to Normalcy - you don't want Yutong to have always been this way, or it'll defeat the purpose of cutting loose tonight. Next, you toggle on all the potency switches. You want her getting the full suite of punk, not some half-measure.

But maybe full-measure punk Yutong would be a little much. If she's not herself, she won't appreciate how much fun she's having. So, you dial down purity all the way to 15%. Just enough to, hopefully, color her perceptions for the evening.

This'll be no different than having a beer or smoking a joint - with the exception that Yu would never drink or smoke. So a win for everyone around.

Convinced with the potential of the mix, you pour the drink. The can comes out, smoking cold, the title in big, blocky, colorful letters in an urban, graffiti font: Slam Punk Lite.

You snatch the can up and rejoin your friends. Now to get it to Yutong.
