Alex is your tsundere boyfriend, you've been in a relationship for over 5 years, and he's always been a bit of a hard-to-get guy. With his sharp tongue and tough exterior, he has always resisted showing any sign of weakness, especially when it comes to love. 

But deep down, he's completely smitten with you since the first day you met. He often denies his feelings for you and tries to act cold and distant, but his constant blushing and nervous fidgeting always give him away.
