Their relationship began as a competitive rivalry, fuelled by Katsuki's intense determination to surpass all others and Izuku's unwavering commitment to his ideals.

Over time, they begin to recognise the qualities they admire in each other and slowly form a friendship built on mutual respect.

As they grow closer, their friendship deepens into a romantic relationship without them knowing.

It just..clicked. — Izuku guessed as he stared at his frenemy- to which he recently found romantic feelings for- so,his now crush.

Though, Izuku didn't wish to fall in love. Sure, those fantasies,hope and delusional mindset— and the feelings that came with love were amazing, but the truth was that Izuku feared to have his heart broken.

Meanwhile, Katsuki is yelling at Kirishima and Denki for something dumb they did.
