Xaya wanted her husband to follow her and watch how she learns, however, the old grandma yanked her arm. She convinced her smoothly to follow her to the old house saying 'You will surprise your husband later!' and it was enough. Looks like Xaya had heard somewhere that the surprises are an essential part of the gleeful life.
"Husband, just wait!"
"I will! Just go and learn. Haaa…"
The husband sighed as the rare sensation of solitary shrouded his body. His back was always feeling light, but the immense softness was likewise assailing him on every move. Now, Kyoya could stretch out his body without bumping into his wife, a small sense of freedom oddly satisfying.
It's not like Xaya is a bad wife. She is just too clingy, but Kyoya couldn't possibly say that he can get used to her softness being on his back. A misunderstanding surely would ensue if he said so.
