Heartwarming / Ar tonelico: Melody of Elemia

• The scene where Lyner administers the Life Extension Agent to Aurica. It's a painful process that all 3rd-generation Reyvateils have to endure every few months or else they will die. For Aurica, everyone who previously administered the Agent did so without trying to comfort her in any way. Lyner was the first one who even bothered to help her relax and even let her hold onto him.
• Progressing deep into Aurica and Misha's Cosmospheres involves Lyner crafting items that help both heroines restore their Mind Guardians. Even though both Don Leon and Hama ruthlessly Troll Lyner, he helps revive them for the sake of the heroines.
• Reaching any True Ending, whereupon Mir thanks the heroes for saving her and conveying her gratitude through a Song, EXEC_RIG=VEDA/.
• The way Aurica proposed to Lyner using music boxes.
  • Heck, nearly all the ending levels of the Reyvateil's cosmosphere where they confess their love for their partner.
