The Balanced Equation

The golden rule of being roommates: Mind your own business.
But that rule is about to be shattered before the semester even ends!
When sudden dormitory renovations throw the campus into chaos, fate plays a cruel joke. Khaofang, a fiercely disciplined accounting major who despises disorder and has never been in love, is forced to share a room with Rain the engineering faculty’s notoriously hot, reckless playgirl whose romantic scandals are daily campus gossip.
One goes to bed strictly at 10:00 PM; the other stays up until 2:00 AM.
One demands absolute silence to study; the other blasts hard rock music.
Their clash is instantaneous the second they step into Room 809, prompting them to build impenetrable walls and draw a definitive boundary line down the middle of the room.
But the chaos violently multiplies when Rain's complicated past catches up with her, forcing her to beg the roommate she barely tolerates to play the role of her 'fake girlfriend' just to ward off a swarm of persistent admirers and a relentless ex!
From strictly enforcing an invisible boundary line to suddenly holding hands, sharing meals, and putting on a desperately convincing show for the entire university. Amidst the forced proximity and the unexpected, profound care hidden beneath Rain's infuriating teasing, how long can Khaofang a girl absolutely terrified of love keep her fortress intact?
Especially when her 'fake' girlfriend starts making her heart race entirely out of her control...
"Remember, we are just pretending. Do not cross the line, and absolutely no going too far."
"Sure... but you'd better guard your heart carefully, Four-eyes. Because if you accidentally fall for me... I'm never giving it back."
