Yup been there done that.
Mine was an office romance so we tried really hard not to let our colleagues and friends know about it. But reaching ofc early to have breakfast together in ofc canteen, staying late in ofc till 10pm even when work was less, going to ofc on weekends 😆 , endless chats on ofc messenger (no whatsapp those days), going to meet each other for some work related queries 😆
I can really co-relate to super fast confession from Dev as my BF then proposed after just knowing me for 2 months. And I was like how can you take a life decision so fast at age 23yrs and said NO initially followed by YES after 2 yrs. 😉
We told our parents after 7 yrs of courtship which included us staying in different cities, countries, continents and now happily married.
