Want you to eat my rice ball with 〜てほしい

Grammar Explanation: Want you do to something with 〜てほしい

As they start a shogi game after school, Ayumu hears Urushi’s stomach growl. She pretends there wasn’t a sound, but Ayumu realizes she’s hiding that she’s hungry. If he can avoid embarrassing her, Ayumu has the solution in his school bag.

歩(あゆむ):: 「オレのおにぎりを…　センパイに食(た)べてほしい…！！」; “I want her to eat my rice ball.”; Literal: “My rice ball... I want Senpai to eat it...!!”

With 〜てほしい, the person you want to do the action can be marked by に.

3オレのおにぎりを is the object of 食(た)べる
