Kairi also has one sad story;first lost her mom when too young and now her father living in Dubai=jail,no help for her or her siblings. In desperate need of a mother figure,got that in Mairi and since only K can control her,here is another reason for K to move in and Yug to tone down.
Mairi adds a lot to Yug's trauma-how to heal if he hears Lata Lata all day??To hurt him more,now M behaves as if she's the one who has to go to school.
Lata again,really was about to leave Yug and he wasn't happy about it,Mairi tried to stop him. Adding one more piece to the puzzle
Those neighbours...so shameless,invading K house like that
K sold her mom chain to bring the money
but she got M chain in return.
Yug playing chess alone,sad life
