You do know that Kuya is also a term for respecting elders or people with higher position right? Like Japanese calling their seniors "senpai".
i do acknowledge that but would you be in a romantic relationship with someone you would call kuya? because given that kuya is used in the context of older brother, older man or some man in a higher rank, would you dare be in a romance with them? have you ever seen someone call their romantic partner kuya? i am filipino myself and i just find that weird. i am not against the romantic relationship between hugo and noah at all. in fact, i ship them. but that detail made me question the game a bit. sorry for the late reply
