It's not in Turning Point 2, it's the very last event in the update, no idea why the gallery put the Turning Points at the end.
After the sex scene with Yuto, and getting his favor down a bit, you have to go the tattoo/piercing shop, talk with the lady there, get Yuto favor down to 105, buy the pills, make the concoction in the kitchen, and then give the concoction to Yuto.
There's some gaps in the explanation there, mostly as there's zero guidance after getting Kord to 100 favor. Anyone interested, doing my best to flesh it out better:
- After getting Kord favor to 100, expect a sex scene with Yuto. There's three options, the top two give 10 favor to Yuto and the bottom one gives 5 favor. Save yourself the trouble and pick option 3.
- The following day, the Body Modification shop should be available during the Day. Visit and run through the conversation with the owner, necessary to progress later.
- For the next few days after, fast forward time to Night and visit Yuto in bed. Request fingering. The fingering mini-game is pretty jank, so either leave it to count down the 15 seconds to fail, or left click the bombs when they show up. That will speed it up a small bit. After failing, you reduce Yuto's favor by 1 each time. Tedious as fuck, but the only way to reduce Yuto's favor that I know of that's been posted in the thread. If anyone knows a faster way, love to add it here.
- Once Yuto's favor is down below 110, a scripted story event occurs the next day with Lisa getting food/condoms and an NPC offers an XXL condom. Run through the conversation, Lisa accepts the condom, and upon returning home shares the news with Kord. But Kord plays hard to get as Lisa isn't desperate enough. Conversation ends.
- Return back to visiting Yuto repeatedly at night, failing at the fingering mini-game, to get Yuto's favor down below 105. Tedium, my old friend.
- The following day after getting favor below 105, there's some random conversation had but it doesn't really matter. Once free to Day roam, visit the Body Modification shop and the shop lady will have a ! mark, so talk to her. Lot of yapping later, she sends you to the Midnight Store via teleport and you can finally buy stuff there. The only thing available is sleeping pills. Time to medicate Yuto! Buy the pills.
- After acquiring the pills, visit the kitchen during the Day, and you should have an option to make a concoction. Click that, it will then move to ask for what to add. Click the sack button on the bottom left to open your inventory, select the pills. Bam, Lisa starts cooking. A budding Walter White. Let the animation run through and finish, you now have the concoction for Yuto.
- That following Night, visit Yuto as before but instead of asking for shitty fingering jobs, select 'Give concoction' option. The rest of the sequence plays out on rails after. Lisa finally gets the Kord Kock. Everybody liked that.
That's the end of the 0.12 content.
Personally, looking forward to her bouncing on it next. Also, the natural evolution of the Kitchen scene with her hair handle bars for assistance.
