anniversary ideas!

so my boyfriend (20M) and i (19F) will have been together for 4 years on the 8th of this month, & i need advice on gifts/surprises! i try to google ideas but everything anniversary related is like for a husband or a grown man & he doesn’t really need personalized golf balls or anything else i find online. obv it’s hard because you guys don’t know him + it’s pretty soon but i was just hoping for some ideas for something special we could do together for our anniversary! money is kind of tight because we’re saving for our first apartment, and it’s difficult to book anything because it’s so close to valentine’s day, but any help/ideas are appreciated!
