yeah i agree ,me too havent seen them anywhere offscreen but when i saw their grand entry i was zapped ....the way they posed fr the kiss and if ones watched closely...u will see that mona tries to back off but apu holds her back and then mona turned back blushing and apu was looking at mona (blushing of course)
when dadi said to mona that if apu wasnt married,he would have married him,he looked back at mona and said " zaroor kartha badi mom"...it was sooo cute
when they came in ....watch how apu holds monas hands....it was sooo like a couple and not all like friends
then came the episode....i mean when apu blurted out "bathroom mein acha gaathi hai" they just cut the shot and showed hitesh's face instead and then they showed mona sayin "aapko kaise patha"
lastly...the sr scene which he enacted with dadi and when he came closer,it wasnt dadi but mona who looked embarassed and closed her face and then apu looked bact at her and she was still closing her face and laughing
actually the entire episode,he looked at her for reactions whenever he was asked something,he wouldlook at her
