Too many kanjis I couldn't read >.>
Basically:
>> Satou in his apartment, thinking if the whole dating with Yachiyo and gets Kyoko's approval is a dream
>> Someone comes and it was Yachiyo, Satou thinks his dream this time is too awesome XD
>> Yachiyo comes because she feels the same thing, she thinks their relationship is a dream
>> Both pinching each other's cheek in turn to confirm it isn't a dream
>> Sato then asks Yachiyo to come in, and Yachiyo bring some food and cook for him. They then talk, and Yachiyo tells him that she was having great time at work after all Satou done for her (being kind to her, listening to all Kyouko stories, etc), and finally she says that she likes him
>> It's already very late, I'm not very sure but I think Yachiyo then sleeps in Satou's apartment. Yachiyo could sleep normally while the next day Satou looks very horrible at work due to lack of sleep.
Oh yeah, it's now Kyoko's turn to hear Satou story from Yachiyo XP
