Finally after the wedding you went on your honeymoon with Goo Kim in Japan

Specifically in Shibuya City to shop for your accessories

The two of you went around various shops and went to IKEA for other shopping. Even going to the doll and action figure shop you fought over with him

"Nezuko are limited, leave them for me!" he begged as he pulled out the neatly sealed box not wanting to share it

You pulled the box too you also wanted the action figure because it looked cute ⁠— but he didn't want to share it was his favorite waifu.
