I Want to Spoil Ms. Yoroizuka Rotten

Kurumi's finally in a relationship with the older lover of her dreams - cool, stoic Ms. Yoroizuka, who seems just as emotionless outside the office as she does within her department. You might think shy, younger Kurumi's the one getting spoiled here, but you would be wrong - Kurumi will do anything to spoil Ms. Yoroizuka with all the head pats, hugs, and kisses she deserves!
