   Summary

   Female Izuku Kirishima has been in love with her older brother's best friend for years.

   Unfortunately, Katsuki Bakugou has spent just as many years pretending she's off-limits.

   Now they're secretly involved behind Kirishima's back, sneaking around family dinners, beach trips, and every suspicious glance thrown their way.

   The problem?

   Kirishima is starting to connect the dots.

   And when your brother is Eijiro Kirishima, getting caught might be worse than never getting together at all.
