Hi Mitsuki! I'm glad you're enjoying the game.
I'd prefer to avoid public walkthroughs for now (although I don't mind if someone else wanted to post a video walkthrough or similar).
However, a more specific hint: Your goal is to get close to Carlos such that he comes out to you on October 6. This will happen if he likes you but has NOT freaked out about it. There's four "freakout" points, so your goal is to avoid all of those while getting close to the two of them:
On August 27, don't go swimming with Carlos
On September 8, ask for nachos when you go to the movies with Adam and Carlos, causing Carlos to go with Adam to get them
On September 24, don't go running with Carlos
On October 1, don't seek Carlos out at the frat
The other requirements should be fairly straightforward, especially in Easy Mode. I'll also note that intervening when the shit hits the fan with Robert will give you a lot of relationship points, and taking Jake to Q&A (instead of Adam) is also useful.
