I'm looking for 2 oneshots
The first one has MC liking a girl and said girl likes a boy but isn't brave enough to confess. Girl then practices confessing with MC telling her "I LOVE YOU WILL YOU GO OUT WITH ME" repeatedly, in which in one instance MC replies '"yes I would" or something, suprising the girl, but MC immediately saves herself and told her that's what she think the boy will reply with. It wasn't an angst I believe, I recall MC being really understanding of the girl falling for a boy and acts chill throughout the story.
The second one has MC meeting her "ex". Flashback, MC's friend confessed to a soccer player or something and got rejected. MC comforts her telling there's a lot of stars in the sky or something and so she asks MC to 'go out' with her for summer but only for fun because since she got rejected she now has no plans for summer. Then on the last day of summer, when they would break up, friend said something along the lines of "even if there's a lot of stars in the sky, I can't reach any of them" in which MC replies "even if you can't reach the stars, I'll stay by your side down here on earth" before running away. Flashback ends here, and friend said that after they graduate she has dated several men but none of them worked out, it didn't feel as fun as the summer of them dating, and then friend asks MC to go out with her again, this time as an actual relationship.
Actually now that I written those 2 summaries, they just might be the same oneshot (though not 100% sure).
