Omae no Nakigao... Kuru! Saenai Douryou Kyoushi wa Bari Tachi no Do S

Rinko Asakura may be beautiful, but she's as strict a math teacher as they come. She's expressionless, never smiles, and her students call her the "Ice Queen," but her new colleague, Mr. Kubota sees through her instantly. Mr. Kubota's also a tough guy to read, but he consoles Rinko when he notices that she's shocked upon seeing the man she secretly pines for getting intimate with another female teacher. They go out for a drink, she tells him that men are afraid of her expressionless face when they get physical, and he suggests giving him a try. The next thing Ms. Asakura knows, she's finding out that Mr. Kubota isn't the mild-mannered man she usually sees at school. Mr. Kubota, on the other hand, is unbelievably aroused when he sees her tears. What will happen to Ms. Asakura when she breaks the school rule forbidding romantic relationships between teachers...!?
