Does Lily like me back.

So there’s this girl in my English and French class named Lily who i find extremely cute adorable and sweet I like her hair and how kind she always is.Even though most of what I have heard is that most people in my school think that she is extremely hot she Is kinda one of the popular girls at my school and kinda in that group but I’m introverted and really shy.Shes my crush.

Anyway so well funny thing is I didn’t know they really existed until like a month ago when my English teacher changed the groups that are in so I’m now sitting across from lily facing her in a group of 4 other boys and of course Lily.And when we start talking she mentioned that me and her are in the same French class. Then the conversation turned into asking about nicknames and she now calls me jet sometimes. also every day when she gets to class she says hi to me and we talk a little.But some times her foot touches my foot under the desks I’m like thinking it’s an accident so move my foot back then she moves to touch it again and it repeat until my foot is under my chair is this on purpuse. Then like a week ago she for some reason wanted me to pick the color of the shoes she wanted to buy then and now wears the same shoes I helped her pick out the color for every day.Today she some how had a flower asked me if I wanted it and gave it to me i blushed the whole period. I’m holding it right now.

TLDR my crush Lily give me a flower and gave me a nickname Jet

So does she like me back?And what to do should I say something sweet like “Hi lily where did you get the flower I’m asking because it’s nice just like you”also is that sweet.Should I say that or do something else.
