'focused' on the journey of how the mcs develop their feelings for e/o (not like more on comedy w/ just a touch of romance, not more on friendship b/w girls, etc.).
Something like Always, Doukyuusei (tho I'm not looking for shounen ai movie as of the moment)
Quite ok - Our Times, Crazy Little Thing Called Love
not heartwarming, but focus on 'journey' of MC - Bokura ga ita 1 & 2
