I put my faith for Shii's story..
I bet he's mischievous and tough...with a 'lil bit mystery

HE really let me down....no proposal thingy whatsoever...
Felt like I just read After End of event...just that...

My Sweet Proposal is stories are much much better that this one
Shintaro's story only has a very little conflict...maybe because they should put every character around Yamanote's mystery
If I guess it right, they would be:
Suwa and Masato: someone who get sponsored by Yamanote Group (I forgot if Suwa really sponsored by Yamanote or other's group)
Amasawa: son of the Chairman
Horai and Shii: ones who will reveal the mystery
Shintaro: Chairman's bodyguard
Naoya: still a mystery what's his connection with Yamanote Group...maybe the casino belongs to Yamanote?
I hope Shii stories will put the curtain around this Yamanote mystery...since it's what get me hooked to Sweet Scandal
It would be too bad if they let this red string just gone unsolved just like that
