Do you really want to know?! I can give you the spoiler if you don't mind spoiler at all.
SPOILER (just in case there are others who don't want to be spoiled)
Mitsuru will end up with Azusa the tsundere and they'll become a happily married couple at the end (few last chapters). While Shino had her own partner/boyfriend. You can check/read the raws on the link below.
Oh they're still planning it.....hahaha, guess since it's been a long time that I kinda skim the raws so I'm not particularly remember the details. All I remember after the whole fiasco with Azusa's dad, Mitsuru finally being approved as her boyfriend and they live happily ever after just like the other two couples.
Thanks for those details stuff.
I just want to confirm, have anyone already read the raws? if yes, can anyone tell me whether Misturu will ended up with the short hair girl or Azusa? (the mean girl)
