Intro: Now for the ship including the main character! This ship might as well be the Kataang of My Hero Academia, since I consider Bakugo x Ochako the Zutara of MHA. But anywho...
Proof: I wouldn't exactly call it crushing on a girl at first sight with Izuku, but considering his inexperience with pretty/nice girls (his words), I wouldn't be surprised if that were the case. And all of a sudden... the tables flipped.
We all fully expected to see Izuku show obvious signs of crushing on Ochako (which he did at first), but it somehow became the opposite. Instead, Ochako is the one showing obvious signs of a crush while said crush is somewhat oblivious. It's great. She has to deny being in love with Deku all the time.
Unfortunately, she has not so recently decided to push her feelings for Izuku aside in favor for accomplishing her goal of becoming a hero. Fortunately, their friendship has not changed and Ochako continued to exhibit sighs of a crush.
What I think: This ship is great. These two are adorable nuggets who we must protect at all costs. Their relationship is something I strive for. I can't get over how much I love Izuocha.
