According to me, as of now Guddu's feelings fall within the category of something more than crush & less than love.
She had shown all symptoms of having a deep crush,
----> stealing glances at him after the raddi wala kand
----> Covering that up by putting up an attitude when AJ looks at her
----> Creating situations to get his company i.e. rangoli kand
----> then during kathoor's entry, when Kathoor sat on his sholder & he told her to take it away as he has work, the way she taunted him indirectly telling kathoor, "sahi hai !...waise bhi inn uncle ke pass rehneka koi faida nahin hai, masti wasti tih karni aati nahin hai, sirf gussa karna ata hai !... Humare saath raho tum, hum masti karenge saath mein."
it gave an idea that somewhere she longs for his company.
----> then the way she tries to imitate his style
----> Everytime she gets defensive whenever AJ taunts her or shows sarcasm.
Like in yesterday's scene when she commented why is he standing tera & AJ taunted her saying her nazariya is "tera". In normal circumstances she could have come up with a better comeback but instead she got defensive complaining how he doesn't understand her jokes.
But in some instances she has proved much deeper emotions are involved too,
----> she kept defending AJ in front of Dutta even when she was tied up & kept at gun point without caring about her life
---->during the kidnap at one instant before AJ came, she wished AJ stays away from this for his betterment
---> She couldn't bear to see AJ broken after the painting got stolen or after the chit drama
Love is very complex, & there are several types of it. For Guddu it will be her 1st.
& i guess Guddu hasn't witnessed any happy in-love couple closely in her life as her mom passes away long ago, & she grew up under Kaushalya's eyes & i don't think kaushalya-bhushan are any happily-in-love couple.
So it may take a lot of time for her to realize her feelings.
I am too exited to see how they fall in love, how their feelings develop & how they realize it !
lets see how cvs play this out...
