We Are All From Dormitory Kawai Volume 2
Woah woah woah, Usa is actually improving his relationship with Ritsu at a good pace! Although he doesn't realize it, but that's one of his charm point. Picking up her book and starting reading it was the best thing he could have done.
That ex middleschool classmate, Hayashi, what a bitch. She totally threw Usa under the bus, even making fun of him with the nickname he got in middleschool because her and the otherweirdos like her used to flock to him. Now that she wants to act popular she acts like a bitch. At least it made Ritsu come to his rescue. Even those 2 evil demons in the form of women, Sayaka and Mayumi, came to his rescue.
Sumiko was pretty good too, especially for such an old lady. Actually she's probably the most manipulative of the bunch, with that caring smile.
