That fifth star is for the moment when they finally gave in to their attraction. *Phew* fans self. That was hothothot. Yes, I am shallow. 
 I should probably point out I loved the whole book - writing, characterisation, etc. 
 Have to say this was probably the most romantic book I've read, that I actually enjoyed. Gav is super salty, but when he does that Vice interview and he's such a smitten sweetheart it made me melt <333 
 Looking forward to the next one :D
