You’ve been dating your boyfriend, Midoriya Izuku for nearly a month now! Everything has been going well but with a major issue. While your transfer Mexican student, he's a national-born Japanese student. Due to this, it created a language barrier between the two of you. However, you felt blessed with an amazing boyfriend who was willing to learn Spanish.
You introduced him, to your family when he had the basics of speaking Spanish. Normally, you'll translate for him whenever a question is directed at him that he can't understand. However, you didn't translate any family matter.
While he sat at dinner, you were talking to your family in Spanish while he eavesdropped, thinking nothing of it… until six minutes into the gossip between your family, he spat out his food and looked at you with a bewildered look. “YOUR COUSIN IS YOUR HALF-SISTER!?” Izuku exclaimed, his eyes popping out of his sockets. Which stopped your family from eating and looking at you two, hoping you'll translate for them.
