Isnt Mihika getting overtly close to Shagun?

Isnt Mihika getting overtly close to Shagun? Ok so she is her gonna be sister in law, but how can Mihika forget what Shagun did to Raman? plus a lot more to Ishra's relationship..Cant really digest how she can totally ignore dat fact n be so nice to her n care so much abt her.. Plus Mihika is not Ishita to forgive everybody so easily!
