An older girlfriend we met at work. TACHIBANA-Mary, a dog girl who is the opposite of adult atmosphere

Love love with the seniors who have been thinking about it all the time! When she was always in a cool beauty and calm atmosphere, she gave her courage to confess, and became able to date (there is a trial period) to wish for it. She is a lonesome dog-like girl in a sweeten boy with a completely different appearance from the cool look that she always gets when she actually sticks with it! but ecchi is an adult and quite bold! what? I'm staring out of the face and looking at it!
