You're expected to get every student to at least Bond Lv20

Anything beyond 20 is reserved for the ones you autistically hoard gifts for, the ones you take time to get them to five stars, and are willing to put a lot of time and effort into

You should use gifts for regular students though at least until they get to bond 20 to unlock all their momotalks
Here's how you give gifts
Hold the gift up in the air, look at each student, there will be either a happy face or a normal face above each student
Only give the gifts to students with the happy face, that means that they like the gift
You're wasting gift resources if you're giving gifts to students they don't even really like, unless its a student who has no favorite gifts, or if you're just really autistic about giving gifts to only one student
Otherwise only give gifts to students who really love that particular gift. You want this sort of super happy face to appear above a students head before you give a gift to them, that's the most effective way. It means that's their favorite gift, so it'll give the most bond points.
