Fluffy Cdrama and/or Logical FL

I'm basically looking for recommendations in two areas. Can be one or the other.

1) Fluffy CDrama- I loved Put your head on my shoulder, Go Go squid, love O2O etc. and was just looking for more rainbows, bubbles and fluff.                                                                                                                        2) A logical FL, whose decisions MAKE SENSE in the context of the drama and has COMMON SENSE. Like Story of MingLan, Love me if you dare, Lawless attorney etc. They don't chase after ML and just always make SENSIBLE decisions.

Thank you if you can think of any :)

Well intended love
