Then, in the end, Bertia thoroughly explained the meaning of the event to Kuro once more, and after Kuro was properly aware that the bouquet now belonged to her, the [bouquet toss] ended, but… I’m a little concerned with how Kuro, after Bertia’s explanation of, “the person who obtains this will become the next happy bride”, stared at Zeno who was standing in a corner of the venue
A few chapters after:
The figure of Zeno who scolded the black fox with a serious expression was very heartwarming as if he was a pet owner speaking with his pet, but from Zeno’s perspective, it would be unbearable for his pregnant wife to be lying on a cold ground and could even get accidentally kicked.
Being her fellow spirit, Zeno was obviously aware of this, and there seemed to be occasions where the adult-formed Kuro went to play to Zeno’s place in the middle of the night.
