(This is in minecraft by the way)

He will most likely try and be cliché and get you flowers with chocolates in a friendly way and sort of as a joke as well to be honest.

If he wants to be extra then he'll ask around for advice as he has no clue on how to treat you for valentine's, whether it be friend-on-friend or not.

Fundy would likely be the one giving him advice as he is surprisingly good at what to do in these kind of situations.

Ranboo would probably take you into a clearing in a forest with flowers and bees everywhere, but if he doesn't do that, he'll probably take you to his house to just sit and talk since he wouldn't know where to take you, despite the advice given to him by Fundy.

You would probably give him a few letters and a bit of chocolate but nothing over the top as you don't want to appear too tacky or clingy.

He would likely get a bit bashful at the kind gesture and say there was no need but we all know he deserves it. :)

Ranboo would over all be a tiny bit romantic but not in a crush sort of way, it's probably like just him trying to repay you for your company and kindness as he thinks you have gone above and beyond for him.

We all know that we would do a lot more for him if needed but we don't want to overwhelm him so we don't do much on special occasions apart from birthdays or Christmas, but even so, we do at least get him something small on small occasions because he deserves it.
