Can you give me reasons why we ship IR
there are so many reasons why ir makes most sense and are actually a couple i want to root for.
their chemistry - unlike other potential pairings (canon ones especially) is one of the best ive seen before. a couple that can support one another but also tease one another. they easily have the ability to be in a relationship anywhere from serious to light hearted
their devotion to each other's safety - ichigo mentions wanting to protect his friends (honestly his main motivation for all he does), yet he takes extra precaution for rukia. he tries to protect her from being taken to ss, doesn't want her off by herself in hm, etc. rukia protects ichigo on her way to ss making sure his life is spared, and even before knowing each other well made sure to protect him from the hollows and himself. putting someone's life before yours is a pure way to show love.
they know each other so well - there are times in the series where rukia and ichigo recognize what the actions of one another mean versus their words. so when ichigo sees rukia after surgery in tybw arc, she immediately knows something's wrong, like when he's a hollow as well. ichigo knows rukia's loyalty to her brother in their first encounter before she's taken prisoner isn't because she really thinks ichigo is too lowly to grab byakuya's robe. even early on, they are extremely aware of each other's emotions.
these are just things that foundationally make a strong relationship, and there's other reasons beyond that
being the sun to the moon
connected by the string of fate
death and the strawberry being literal chapter titles in canon manga
the way they look at each other
can call out each other's bs
mirror ichigo's parents in a significant way
and while ichigo was sad and unable to do much of anything about losing powers and rukia, rukia was trying to give him his powers back
and really the complete devotion ichigo had to saving rukia (when the poor girl was resigned to her own fate already) was the most romantic storyline in the whole series.
really i could go on and on about why they would've made such a great romance
