Someone who worried about him is Cagalli.

@@bhudchotabhisitkul3967 Only Cagalli. She's the reason he's alive.

@@khadz1705 yeah true

I mean. Cagalli? She literally cried lol

@@meikisaragi1445 But Cagalli was the only one who knew what Athrun was going through. She was the only one who was around him when he tried to end his life. Her words gave him courage. These words "To live is a fight" even became a philosophy he uses in the future. But, except for the woman who loved him, no one else seems to realise what he was going through. Everyone else's (Lacus, Mu, Murrue, arcangel crew, Waltfeld, eternel crew) attention were fully on only Kira. Cagalli was the only exception. It's sad that Athrun's friends and partners often depreciate his hardwork and difficulties. Cagalli is the only one who actually sees all that Athrun does for others and showed appreciation for these actions. Kira and Lacus has never once thanked Athrun for all the things that he's done for them. A mere "thank you" would not be too much. But, even that we have never heard any of his friends excluding Cagalli say to him.
