Sanae: “Aren’t you referring to them a little to much like family?”
Lady you approved their relationship, let him live with you guys a few days so he could attend cram school during winter break and is friendly with their family. It’s safe to say that the future is already set in place.
I pray for this poor boys sanity and strong will once they hit puberty. Seeing Nana in high schoool makes me think Mana is going to be similar and with how much she hugs and cuddles her childhood friend, good speed Shou.
