I take back what I said earlier, the new Castlevania series is far more than just “Okay”.
Since it's Valentine's Day.(Have the RFA+V+Searan) I would love to ask if you could do MC and her brother spending Valentines together. The others couldn't spend time cause they were busy. So once they have some time to spare them look for you and see you are your brother hanging out. Yet you are siblings so you sorta close to each other and some things seem romantic. The others don't know you have a brother. So how would they react? If you can't do it, it's okay. Happy Valentine's Day!
