Also possibly this
Does anyone remember like a yaoi manga, that was about a guy who received a robot as a gift from his friend. But then he found out that his friend acc meant to sent him another robot and that wasn’t his gift? That Robot was also like very strong and stuff and it escaped from like some facility? I think? I hope someone can help me find that manga (ik I’m bad at describing sry y’all )
