the reason why it’s titled as “seasons of blossoms” bc it portrays different seasons of life that also focuses on different people. So each of them (characters here) has their own season where they are the center or protagonist. So nope they aren’t just randomly introduced without a meaning, they have their own stories which i recommend you should read since they’re also good

Like the fr adult couple is fucking boring hello??? They were introduced from nowhere and like I couldn’t care less about them …. Oh no so sad ur mom was scammed doesn’t mean you can slap people also the dude is annoying as fuck. Ohh bohoo I’m a little bitch, like lock in hoes. LOCK IN. Like okay ur the older brother of another couple (that i don’t necessarily care about either) WRAP IT UP.
