Well, there's a scene identical to the one you describe in a shounen ai!
The manga is: http://www.mangago.zone/read-manga/seven_days/
And the scene you described: http://www.mangago.zone/read-manga/seven_days/an/seven-days-chapter-9.html/16/
I only remember one thing. There's a girl who likes a guy, but the guy is smitten or tied to his brother's wife/girlfriend. In the end the wife returns to her husband and she is seen running towards her husband who is standing on a staircase. He holds out his hand and she places her cheek in it.
