I can't believe that you all need a walk-through wen the game just came out and almost has noting to it. ... I'll give you a short one right now.
1. Play game, try different things and see what works.
Day one: look at every room try and find the ! and click on it. Go to her bedroom and click on the closet then click on her bra and shirt, then go to the shower. Go to kitchen... Go into his office and pick up the ball like thing near the window, then go to her bedroom and click on the Gray box on the right. you get item.
Day two: do the same but try talking to woman, evening time.
Day three: do the same as and use the new info from talking to her to advance the game. Also the disk puzzle is hinted at in the letter you read, if you skip it you will have a hard time salving it. No I'm not going to tell you the answer, play the game.
Day four: as above, do this until you have all the info you need to get into his PC. Once you have the PC access then you can go into her closet and input the code, and get into the next part of the map. (unlock the door on the right once up there)
Most of the game is the same, just talk to her and check each room every day and at different times (by resting in your bed) and see what you can do there.
When asking her for yoga she is on her balcony reading, click on her closet and bottom right you will find the cloths.
This is really not hard.
