My Heart Is Sealed in Ice, and My Battle of Wits with the Phoenix-Proud Heroine

A reborn man who, in his previous life, had his heart crushed by a goddess after acting like her lapdog.

But even after being reborn in another world, he still has to go back and forth with a Phoenix Queen.

She hits me, insults me, uses me, kicks me out of the party when she's done using me, then tries to break down my defenses and warm up my concrete heart.

How familiar are these tactics? She wants to keep her lapdog around, but she's afraid he'll take off.

But...

“My tongue's too stiff. I can't lick anymore.”
