I have gathered all of the Tsukiuta icons and made this (there are ones that I left out). Everyone grew up so handsome.
Kokeru (sorry, a lame joke from the anime) Kakeru looks like he hasn’t changed at all. His bangs are shorter but that’s everything. I bet his height hasn’t changet either. (Okay…he might became taller)
Hajime from young charming prince became the king, for sure. Also his hair looks better now.
Koi has changed a lot and became seriously good loking, isn’t he? He is not a little boy with hairpins anymore,
he is a man with hairpins now, I suppose, that’s sad, because he is the youngest among the boys.
As for Haru, he looks more handsome and serious, just like megane-san who is alwas with him.
Arata looked like an impudient but handsome brat, but now he looks like a Casanova.
Aoi from the cute neighbor boy became the prince charming in white horse. Okay he hasn’t got a horse but still… he looks much like much better just like everyone else, so nice work boys, I’m so proud of you.
I’ll also post the Procella version
