Well first of all my bad cuz i didn't quite catch the meaning of your question but not because your grammar is wrong haha i'm a french guy so please don't be mad at me~
Then to answer properly this time (i really hope so) :
- You should see in gil's character menu the count of 'like' and 'love' point. Starting from day 2 try to choose all the different options and see if the like point increase or decrease (towards the end of day 4 pay attention to the points and a pleasent thing should start ;D).
- It will take some time of course and there might be one or two tricky options but overall it's not difficult. I did it this way and ended up with 49 like points and 5 love points at the end of day 5. I don't know if that's the highest you can go but i couldn't so......yeah.
- Doing it this way might be wierd cuz you roll back to max out the points, but you can do it by guessing what Gil like the most : he's a coach to begin with so he like things that coaches like (that's wierd to say but idk how to say it otherwise :p).
With that i really hope it can help you out and if it doesn't then i can hide in a cave with a bear to wash my shame (oh hi there mr. Parker hehe...........) cuz i would not answer you question right for the 2nd time and..... kill me if that happens pls :D
Have a good day/night/time playing After Class/idk what ur' doin but have fun ;)
PS : I hope that my grammar is not wrong btw :)
PS 2 : here's a proof from my save with gil for the points
