Who do I choose? (To date/flirt with)?

I would say the second girl and first guy, the first girl doesnt really consider your feeling and seems to hang out with you for fun. The second guy is not worth the heartbreak, especially since you barely know each other. The second girl seems to be someone who would be a good friend and might develop into a girlfriend, the first guy seems to be someone who you want to help and should and maybe be friends with
