Great manga but the end..hmm:| I felt bad forAyaka,it seems like she had crush on Kanako,after watching her and senpai,in my opinion Ayaka is the one that's left alone.In the other way,it seems like Kanako,at first had smth like crush on Ayaka too(?),but after dat "advice of becoming mature"from senpai she got into that NSFW so she fall in lone with Senpai.Senpai seemed like a stalker xD Pretty nice tho,but sad bout Ayaka:| :)
