Caluri is the relationship between Cala Rose and Yuri Lowell of Tales of Vesperia.

Timeline

Early Days/Imperial Knights

• Cal and Yuri meet when Cal is 7 and Yuri is 8 -- Cal had just run away from home, and she's found in an alley alone by Yuri and Flynn
• Yuri and Flynn bring Cal back to the orphanage with them
• Despite butting heads and arguing like a married couple, Cal spends most of her time with Yuri and Flynn until Flynn is forced to move to the Citizen's Quarter
• Before Flynn moved away, Cal divulged to him that she's a noble, but decided never to tell Yuri since she's convinced he'd hate her for it
• Cal and Yuri continue to be good friends even after Flynn leaves, although they probably argue even more than before without the buffer
• When they're both old enough, they both end up living above the inn (in their own rooms)
• Cal spends a lot of time convincing herself that she actually likes Flynn because the idea of liking Yuri annoys the hell out of her
• When Yuri decides to leave and join the Knights, Cal is upset but is too stubborn to admit to herself why
• While Yuri is gone, Cal gives up her room and moves into Yuri's old room since she assumes he isn't going to need it again
• Surprise he comes back (Cal is surprisingly happy although she might have been more excited about Repede than Yuri), and they end up stuck sharing a room
• Cal gets the bed (sharing with Repede until he's too big) and Yuri sleeps on the floor
• There are some awkward/funny trope/cliche things in here like walking in on each other changing and whatnot
• Cal gets really used to Yuri being arrested after a while, to a point where it really doesn't phase her any more
• Yuri tries giving Cal "love potions" before bedtime because he's an idiot and apparently a hopeless romantic

During Vesperia Proper

• Cal is actually pretty jealous when Yuri shows up in the Lower Quarter towing Estelle until she finds out Estelle is basically a stowaway
• Estelle asks Yuri if Cal is his girlfriend and Cal literally replies, "I wouldn't date Yuri if he were the last man in the world" which is a blatant lie
• Things don't really progress with them until the party meets with Alexei in Heliord and he outs Cal as a noble and his betrothed whoops and Yuri is understandably upset
• Cal and Yuri have a bit of a yelling match after everyone goes to bed, mostly Yuri not understanding why Cal would keep her nobility from him
• Cal fesses up that she was worried Yuri would hate her for being a noble and she wouldnt have been able to stand it because she loves him
• That's is that's when the confessions happen they are a couple now yay
• Cal gets kidnapped by Alexei along with Estelle because apparently he actually wants to marry the girl he was bethrothed to
• After Cal is rescued and Zaphias is evacuated, Cal finally meets up with her family again in Halure and introduces them to her "commoner boyfriend"

Post-Game

• At some point post-game they get married in Halure because Halure is beautiful and they also have a daughter
