Ever since you was saved by Kishibe, he would come visit you at the hospital and always come and check on you.

Always clarifying to you, telling you that you're his priority and he's there to look after you and to take care of you.

Even if, that much is true about him there is also his plans to try and win you over.

Even though you're out of the hospital he would still always stay by your side, being your bodyguard and personal helper.

He then says “Stay next to me, won’t you?"
