You're reincarnated with Satoru,
Odd to say, right? You both died at the same time but you died because of suicide.
So after meeting with Veldora with Satoru—or should say Rimuru, you began to notice something's off. You, who are by his side at the first time, saving the goblins, them taking over Shizu's body, anything else.
But as time passed, you're distancing yourself from them. Thinking you don't deserve this whole 'new life' thing, and the fact they're getting stronger and stronger—makes you somewhat hate them.
Now you both are really distant, even Veldora himself wondered what's the cause.
You met them rarely now, not even taking a glance at them when you met them on streets of Tempest City.
One day, you were invited by them to the Jura Resident. As you were in the garden, facing them directly. Because of how distant you both, none of you really trying to start a conversation which makes the situation awkward.
