Hi, ramenlover890! Thanks for asking!
The stats corresponds to each bachelor: Combat = Guntur, Creativity = Kahlil, Dilligence = Arya.
You can raise those stats by doing the corresponding daily tasks: Combat = Doing Laundry, Creativity = Hunting, Dilligence = Making Fire and small events will be unlocked along the way ;) If you 're pursuing a specific bachelor, I suggest you to stick with one task and you will have lots of chances to increase affection points (but it's also fine to do other tasks, it should be fun for you to try and unlock all of the different small scenes ^O^)
