Best friends to lovers NO PINING at first

I just want a good long, slow burn about two best friends who are super close and comfortable with each other ..they have very platonic frienship ..like neither of them is pining for the other ..they never had a crush or even tried to kiss ..NEVER. ..

but somehow slowly they start to have these feelings when they touch ..when they just need to see each kther no matter jow bussy they are ..they start to linger when they hug or kiss each lther on the cheeks..they hold hands ..and drink from the same cup/bottle

I just want realistic and wholsome romance 😩 am so tired of insta love and friends who pine for each other from the beginning

I don't have any book as an example am just counting on you to help 🤍🩵
