What do those things mean?
i thought she wanted to live her live as nun, so it's a preparation for that?
Those thing represent her parents and grandparents....
spoiler...
She wants to lay those items on their graves and say farewell to her old life and Kaid for good.
Oh? OH!!
How did I miss that?! I was like huh why those stuff specifically?
Until you guys mentioned it. Even though I just read this manga for the second time XD
I couldn't stop myself from crying when she started listing the things to buy ╥﹏╥
