^ yea the main purpose for ep 9 was for itsumi to get along with ayako ~ right up til now ive always felt some jealous vibes comming from itsumi when she sees ayako with mamoru (kinda like "dont take my onii chan" feeling ~ quite common :3) ~ but now itsumi is a lot less cautious around ayako after getting to know her better ~ she feels that she can let mamoru be close to someone like ayako and the tension is lifted
