(current) himeru and tatsumi were best friends when tatsumi got injured in the revolution incident . he broke his leg entirely , and was told hed never be able to be an idol again . tatsumi was devastated and was worried his fans would feel betrayed by his absence , so himeru offered to succeed tatsumis name as the new himeru, and all was well for awhile . queue the beginning of !! main story; tatsumis physical therapy went wildly better than expected , and since being an idol was what he knew how to do, he decided to give his idol career another shot as a member of alkaloid . since it had been so long since current himeru had acquired the name, he felt bad if he were to suddenly request it back, so he abandoned the name and left current himeru to remain himeru . when himeru saw tatsumi had returned to idol work (when he was under the belief that this was impossible, and wouldnt have become himeru if this was not the case) he was happy to see that tatsumi had recovered , but more than that resented him for leaving him high and dry stuck with an identity that never belonged to him . and thats why himeru hates tatsumi (although rather than anger its more of a lingering stinging pain kind of hate, the kind that makes you lie on your bathroom floor and sob at 8pm and makes you bite your tongue when you see them around), but tatsumi only has bittersweet feelings about himeru (the kind you feel when you see an old friend in public but dont say hi because even if its only a couple feet, emotionally the distance between you is farther than you can walk and you feel like you no longer have the authority to ask if theyd meet you half way)
