Need Help

Okay So My swali is What does it mean when a Guy thinks your Valentine is Cute? So What had happened was I was talking to his older sister and She told me that her brother told her I gave him a Valentine and He told her that He thought it was cute and that He was excited that I got a Valentine from me. So what does this mean does this mean He likes me? Cuz I think He was too shy to tell me this cuz When I gave it to him all He alisema was "Oh Thank You, Happy Valentine's Day." So Yea I'm just wondering if He maybe likes me.
