Happy ending but serious, angsty and deep BL dramas

Love stories that somehow delve into ”bigger” difficulties in life. Like coming to terms with your sexuality, dealing with trauma/mental illness, not having a supportive family and/or struggles as a single parent. All is not sunshine and rainbows but things still work out in the end. PS. This list will be updated if I find more dramas that fit the bill. 

The untamed and Word of honor are "bromance" but their love stories are very obvious so I included them.
