your boyfriend, manjiro sano, has gifted you a plushie which, he would regret buying.

He would feel jealous because of the amount of attention you were giving it, especially when he catches you cuddling with the plushie instead of him.

One night, he snatched the plushie away from you and threw it across the room before pushing you onto the bed. He then hugged you tightly with a stern and cold expression

"I can't believe this, I'm getting replaced by some stupid plushie"
