what if touka giving her parent's wedding ring to kaneki is pretty much equal to her considering that kaneki is also her family? and that since it has given her strength before, maybe kaneki can do the same? i may be looking into things a bit positive T_T but i would like to think it's like that
I interpret this like… when I had rough times, this ring was my strength… you’re having rough times now, so I wanna give this to you so it can give you strength too. Touka will always have the ring as long as Kaneki has it, but I think Touka giving him the ring is more like a… “you’re my strength now?” it’s a bit complicated to explain, it’s very deep, it’s not just a gift or a wedding proposal, it’s more like… Touka’s heart is inside that ring, giving the ring to Kaneki is like giving him her heart, an important piece of her. It’s an act of trust.
