Yes, it was me, I saw your answer, thank you)
SPOILER!
Ahah, I had no chance to resist Raku. In fact, yandere is a type of character which is cool to read about, but which is absolutely not cool to have as a partner in real life. Raku is an exception. He loves obsessively, he really is a monster, but you can trust him with anything: your life, your soul, yourself and everything that is dear to your heart. In addition, the relationship with him seems to be as comfortable as possible. Maximally. So yes, I had no chance.
What am I even talking about here, if at times, going through the game, I begged Nelli not to be too strict with him, although initially I treated him rather... I don't know... skeptical, perhaps? Well, for example, I laughed when he didn't want to leave Nelli alone in the woods, mentioning Sana, because I thought he was the one who killed her. Well, who knows? Sana was Nelli's best friend, after all. Yandere could easily become jealous of her and want to get rid of her so that she would not attract the attention of his partner to herself.
OHHHH, I'm looking forward to it! I am very, VERY interested in how you implement this, but I'm not rushing you in any way)
Thank you for the answer and I wish you success! ❤️
