What does it mean if a woman reacts to the selfie post of a guy with an "I care" emoji after know each other for just 15 days?

I like a lot this woman from my university and I've seen she has reacted this way to the selfie of another colleague of ours during vacations. We all know each other since about 1 month ago. Do you think there has been something intimate between them two before holidays or was that a friendly reaction from her part?

It's a normal thing, don't be mistaken by social media my brother. She can be friendly and reacts to all of his selfies without any intentions of being flirty

She’s interested and attracted to something about you. You two met in person, congregated, and spoken to one another ⁉️
