Okay well I'm want to say some thing to you I'm so in love with the hook the bad boy likes me and you said you need some idea so here I go... I beleive you should stick with. Tyler and her because thats how you wrote the book and the couple ppl will fall for I think you should have Tyler ask her to move i. To hi place she already living on her on (maybe he reason was because she hated seein Claire and cam together) or what ever you like.... And then make their relation ship grow stronger and maybe vein up a past love from her side to get some conflict.. And maybe something can happen to Lizzie like she go hurt or something or goes missing and Tyler and her needs to come together to keep eachoher strong ... I HOPE AOME OF MY IDEAS HELPED YOU
