Izuku Midoriya (Deku) has loved Kacchan (Katsuki Bakugo) for a long time. He knew how much Kacchan hated him, but he still cared. Every now and again, Bakugo would show his softer side. It always made Izuku fall for him all over again. It always killed Izuku when Bakugo yelled at him. It did not stop when he got into UA. But he still had hope. Bakugo hid his feelings well. He cared for the nerd. The shitty Deku. Although he always thought that Izuku would hate him. After everything that Bakugo had done, he wouldn't be surprised. Little did they know, they both liked each other. And one of them, little Izuku, caught a mysterious disease. He was coughing up flowers. He did not know what it ment exactly, but he had a good idea. It got worse whenever he was around his crush.
