As the title says, I'm desperately looking for more charming, hopeful, healing dramas. The type where the lead (generally male or both male and female leads) is currently, or in the past, in a bad place in life due to psychological, emotional, or physical impairment, but now is finding healing and hope (usually through friendship or a relationship). Must have a happy ending, either explicitly or just implied. I know this type of drama isn't common or the "popular" type, but the ones I have come across are true little gems. 

For reference, dramas that fit this request that I have watched and loved are:
Aozora no Tamago (J Drama)
Nemureru Mori no Jyukujyo (J Drama)
Secret Message (K Drama)
Kids (J Movie) 

Others:
currently getting into MARS (2004 T Drama) and I'm enjoying the vibe, but starting to need a break from the overwhelming melodrama
same can be said for Someone Like You (T Drama)
started Aishiteiru to Ittekure (J Drama) and liked the atmosphere, but read a spoiler that thankfully got me to drop it before I got heartbroken

Any help guys? 
From your list, I recommend Missing You.
Mondai no Aru Restaurant
Orange Days

35 sai no Koukousei
Gakkou no Kaidan

Hi
