Yup I usually am fond of characters like Yuki, happy on the outside but really broken on the inside, so I hope Yuki x Ishikawa pwease :3
To be honest, how Sakura fell in love with him because he helped her is so.. cliche and... boring? Like you seriously fell in love with a guy who helped you? Are you going to fall in love with everyone who lends a helping hand??
So the fact that Ishikawa and Yuki have this friendship already established and you see Ishikawa actually paying attention to her and even going so far to be honest with her and willing to try her failures, that's authenticity right there and I'm fully on this ship for that reason!
