--And ML helps him.

Can be emotionally or physically. (gun violence, panic attacks, trauma, injuries)

Examples:

A Tale of Thousand Stars - heart transplant = occasionally passes out, gun violence, beat up

Between Us - insomnia, PTSD, nearly drowning, foot injury

Until We Meet Again - panic attacks


I love to see the ML taking care of the mc.

- My secret Terrius - Both FL and ML continuously protect each other from drowning, gun violence, etc.

- The masters sun - FL sees ghosts but when she touches ML, they go away. Naturally, (but slowly) he starts to protect her.

- Let me be your knight - FL helps ML's sleepwalking issue psychologically.

Chains of Heart - the one ML is often choked/strangled by bad guys and rescued by the other ML. 

Bokura no Shokutaku - emotional support between the MLs.

Self - emotional support.

Not me: both leads are in an gang/gun violence/fist fights

Tharn Type  : ML help about nightmares and trauma due to child abuse. 

Love in the Air- ML went through abuse in the past and has PTSD/Nightmares. The MC helps comfort him and takes care of him. He gives him so much love that makes him feel wanted again.
