-What to do with the condoms, and different endings-
If you don't use the condoms the girls get pregnant and the nurse shows up to tell you the bad news.
Also if you have sex with either of Emi's sisters you don't get the happy ending.
The best thing to do is to not have sex with Emi's sisters and to use a condom with the first three girls and then you get the happy ending.

How to cure Chie ---------------- Once the nurse asks you to help the girls, go up to the library. Go in and look for Chie, you should find her masterbating in the corner of the library. If not, talk to her until she runs away, leave, come back, and try again. When you see her masterbating, talk to her all you can, then ask her everything you can. She'll leave then and your job will be half done.
The next time you're in school, go to the library and look for her again. You'll find her crying and masterbating in the corner. Talk to her and she'll tell you what's wrong and then ask you to have sex with her. Choose if you wanna wear a condom or not. Then she'll say she's gonna be fine. Now go to the nurse and get your "present".

Choose to use a condom or not.When you're done your duty. Go to the nurse for your "present".
How to cure Chisato ------------------- After you've helped the first 3 girls and your getting your "present". The nurse will tell you that if you want to have sex with her you have to help a fourth girl. You have to help the other 3 girls and get your "presents" before the night that you videotape your brother and Aki.
That night, after you get the information from Aki. Go to the Telephone Club and wait, wait, wait. After a while Chisato will call and ask you to meet her in the park. When you get to the park talk to her for a while. First you'll talk about her problems, then you'll talk about your problems. After all the talking you can have sex with her or not. Don't worry about your condom here, because she tells you she's on the pill.
The next day in school, head for the nurse and get your final "present".
-How to cure the other girls 2-
1 - Cure the gymnastics girl. You know how to do that.
2. - Go to the schoolyard, think about Yuko, and talk to her. Then talk to the track team again. Keep going into the school and immediately coming back, until they tell you they don't know where she is. Then look for her until it takes you to the back of the school, where she is peeing. From there it's self explanatory.
3. - After you've cured Yuko and only after... Go to the library. Keep talking to Chie, leaving the library, and re-entering, until eventually you'll see Chie in the back masturbating. From there, it's pretty self explanatory. She'll leave. The next day she'll come back, and her problem will be solved.
4. - The nurse will tell you that there's actually a 4th girl for you to help... And she works at the telephone club. I haven't gotten to her yet, but to get to her, you have to do this.
Day 1: Talk to Doctor.
Day 2: Solve Yuko, Solve Chie
Day 3: Chie will come back and her problem will be solved. The doctor will tell you about the 4th girl.
Night, Day 3: Go to the telephone health. There, you can cure girl 4.
