Exactly, and you remember just before Mei died he said to Akana(when Akane was becoming rebellious)please don't take Keisuke/Sensei away from me he worries about you a lot since your like this(rebellious dying your hair blond ect).
(๑•ㅂ•)୨✧୧(•ㅂ•๑) Yeah.. Akane’s heartbroken then played hooky to hang out with delinquents to do bad thing. Keisuke just pulled Akane back, instead of feeling guilty & helping out, how could Mei yell “Don’t take Keisuke-san away! blah blah blah.."
Moreover Mei acted madly & staggered by himself. Akane didn't do anything wrong to anyone. The problem is.. both Keisuke & Akane haven't known yet that Mei lied so the misunderstanding still has tortured Akane for 3 years already. (〜￣△￣)〜
Can't wait till it gets cleared up
I do get the feeling that Akane is the one Keisuke has loved since the beginning. Mei also knew so he lied Akane about confession & lover to keep Akane distant from Keisuke.
