that is the speciality of all shows be it of any genre
if its youth show- the main lead couple will be together after a lots of ups and downs but will stick together at the end.
if its a typical saas bahu saga-i don't need to explain it but the main leads would never remain happy.
if its an aim oriented show like the heroine has some aim to achieve first they will show her fight to get acceptance by society, then the area where she wants to achieve then the politics faced by her and at the end her aim goes down the drain but she will have an incomplete love story with the hero.
so chill romance will be there they have to achieve their trps for continuing the show,though yes couple kitna tikega iski guarantee kam hai all thanks to trp system par romance kafi milne ke chances hai par agar romance ek episode mei 5 minute ka scene hoga to uss ek romantic moment ke karan 5 episodes ka serious environment wo rakhenge hi
best is switch to youtube or full episodes where you skip scenes and watch only Deblan rather than inquired scenes which are mixed with deblan scenes as stock clearance.
