Iroha is really cute and sweet, but too innocent and kinda gullible especially when dealing with Haruki and his possessiveness which isn't a good trait at all - get that this is a manga and its kind of a "safe place" but this isn't love!
Agree with Tsubasa assessment of the situation (even both her gf's freak out was justified), and think he would be a better bf to her or anyone for that matter.
The fact that Haruki confessed his problems does not mean he's gonna work on them- it's just a justification for how he will keep on behaving - that's not good, cause this can turn dark in the blink of an eye.... i would run the other way if i was her. donno how much i'm looking for an update
