In Between

Gaila and Shane become each other's "in-between" – a comfortable, non-committal relationship they find convenient before settling down with "The One". They initially meet and disagree, but develop a strong connection, helping each other in various aspects of life, like work, love, and social circles. However, their comfortable relationship blossoms into something deeper, but their happiness is disrupted by the return of Shane's past love.
