How do I ask these chubby cuties to be my gf?

Hello fellow chubby chasers and chubby lovers. I am looking for advice because I am just so darn confused that I don't know what to do. So, I have liked two chubby women in my school, they are in the same year as me. I have had a crush on the first chubby cutie since first year and this second chubby girl I met in second year. Now both chubby girls hang inside my friend circle now. I am just so confused because I don't know who to ask to be my gf because I like both of them but in a different ways. I am planning to graduate next year and so I have to make this decision because I don't know if I will be seeing these cuties after I graduate. The first chubby cutie is quiet and a bit of an introvert but once you get to know her, she is so caring and her smile just makes me melt. The second chubby cutie is very bubbly and outgoing. She is a bit more popular and social than the first chubby cutie and she is so much fun to be around because of her bubbly personality. Now I am just so confused because these two chubby girls both have qualities that I am looking in a partner. The first chubby girl has this caring quality and her smile is just so beautiful while the second chubby cutie is just so much fun to be around. Both of them are very beautiful in their own ways and I just cannot choose between the two. How do I ask both of them to be my gf?
