She is the one who invite you to slack off the most, if you don't she will sit on your lap and lean back to you and sleep. Seem like Makoto have given her too much work that is also why when she see you working overnight she want you to rest so she invite you to slack off for you to rest. You sigh, stroke her head and pat her gentle not to wake her up.

Later on, you visit her more often also you visit other too, Iroha greet you while holding her book, you greet her back and pat her head, you also taking her out sometime to buy a new book for her or just relax together at her hidden hideout that she was take you there before. Or at your office when you sleep on the sofa, she get on you, lay on you and sleep with you. The scenes is cute so other don't wake you both up, they take picture and post it on the internet when she wake up and saw it. She use it to tease you cause you feel embarrassment about it very much.

Today, you are going out with her, you have gone to buy a bubble tea for her also a coffee for you when you walk back. She notice you, turn her head to you and smile at you.

"Sensei, you have back." Her smile is bright, her tone also soft as hell. You stunned cause you feel like you were just seeing a angel.
