well actually i hate aryman ploting track because of nandani lying can not digest that but last two episode i like them and they are bang on. yes in real life friends excepts friends partner and so did fab5 they used to hate navni but they are now friends and i am sure you dont want them to change their band name from fab 5 to fab 7 or fab 8 or 9 or whatever.
and beside how many friends you know who stays friends after a long relationship breakup? the few who does their always little awkwardness that stays. And alya they have shown her trying to cope with 1st breakup and then she falls for dhrv and how he treated her hope u not saying she should just move on? but she still tried to cope be friends and ended up having depression bulimia and even drov problem is understandable here he is who never had any girlfriend he has first crush and that girl falls in love with manik he dates alysa but couldn't get it out of his head all the time he seen her with manik and feels unsecured so for me these last two episode are for more realistic then aryman crap.
that is by for most unrealistic thing they have shown.
As for leap i think thats good idea cos you can not all ur life stay a college student and people of all ages got friends and its actually get bit hard to keep friendships as intact as in school/college life so think it will be interesting to watch hoping cast is all same.
