This update is probably the most straightforward update but still confusing asf but the end reward is worth it trust me.
For a somewhat walkthrough
1. the first part is peeking at Melinda and Will arguing.
2. second part is sunbathing with Melinda until you can buy the necklace and give him again at the sunbathing time. You also need to go to linda for pills IIRC.
3. the third part are mostly Will and Melinda event I think Melinda interviewing you is on thursday/saturday at 14time while the other events are for Will at 14 time. The Will event will unlock the strong alcohol for the shop so do it until you can buy it there.
4. fourth part is the Will drunk part you need to make him drunk at 13 and got to 14 in Will/Melinda room after that I think you need to do this 3-5 times to unlock the Laundry room. When Melinda will interrupt you at 13 you need to pick the you will wash your hands in the kitchen so you can make Will drunk.
5. 5th part is mostly for the finish line just to the 13/14 Will drunk part 2 times to unlock the Melinda Sex scene.
